  • One of the science’s big dreams has been to leverage these technologies to radically miniaturize and encapsulate the laboratory: the Lab-on-a-Chip
    People have been pouring a lot of time and resources into the space. There are thousands of papers published on microfluidics. And it does offer tantalizing promise.
    But it is also littered with many commercial failures ... and one very big fraud.
    In this video, we take a look at the microfluidics industry, its pursuit of a mythic ideal, and why they have so far failed.

    It's nice to see you discuss this topic! My first internship had me working for a startup that had designed a Lab-on-a-Chip that had the purpose to bring Lithium measurements for bipolar patients to the point of care. Bipolar disorder is treated by using Lithium, but it has a narrow bandwidth within which it is effective. Too little, and it doesn't have an effect. Too much, and it can be poisonous. Patients treated with Lithium are therefore typically confined to staying close enough to their hospital to regularly have their Lithium values checked.
    The LoC developed by the startup company I did the internship for brought this check to the patient. By just applying a drop of their blood and waiting a few minutes, the LoC would use the principle of electrophoresis to separate ions in the drop of blood and then determine the level of each type inside the blood, Lithium in particular. While the results were mostly for indicative purposes only, it did allow the patient a lot more freedom of movement. Only if the LoC results went 'out of bounds' could they consult their doctor to take immediate action, but the patient could be proactive about it and do so at home, or while on vacation (which the LoC allowed them do take!).
    It may be a small application without a big market behind it, but I do believe that the quality-of-life improvement this particular LoC offered is more than worth the investment in the techniques behind it.

    I tried doing some electrophoresis nanofluidics during my PhD and one of the biggest challenges was bonding my top substrate to my bottom substrate. I really needed two glass substrates to allow the electric field to penetrate the liquid, because a silicon substrate would just cause strong capacitive coupling.
    And bonding two glass substrates with a nanoscale cavity in between is really really really hard! First of all: both of your substrates have to be incredibly flat in order to allow cavities to form. Second: you need to deal with the wringing effect that also occurs in guage blocks. Third: you need to evacuate the air between your substrates during bonding, because you always need a thin substrate to allow you to use a 100x microscope and those substrates flex quite easily. Fourth: most literature on substrate bonding is a variation on anodic bonding, where an electric field assists in pulling the two substrates together, but it always requires some electrode nearby.
    In the end, the only viable candidate I found was sodium silicate bonding, the same technique as the one that was used in the experiments of a Nobel laureate (the experiments in question weren't the ones he had won the Nobel prize for though). As luck would have it, my professor managed to get some students of this Nobel laureate professor to give us a Zoom seminar on their work. When I asked about details and recipes on the silicate bonding, professor X got his knickers in a twist about me trying to get valuable IP from his students (said recipes had already just been published in an addendum to a PhD thesis, his student just sent me a link to it afterwards). 😂 It was both hilarious and sad that a Nobel laureate from a top-5 ranking university was trying to hold back published information from a first year PhD student - from a university that's over 50 places lower on the Shanghai ranking list! - for fear of his own lab losing the monopoly on successfully pulling off a technique. That was the day I learned that the system of "first author gets all the credit" impedes the entire process of reproduction and building upon other people's work.
    Other than the bonding, I'd say that a major impediment to microfluidics research is the fact that small scale production of chips in a research clean room facility is prohibitively expensive time wise. In order for a researcher to freely experiment with a device, they need to know that they can easily procure a new one if they contaminate or break the device they have on hand. As a PhD student, you have to design, produce, test, experiment with and clean each and every single device you make. And if you are to stand any chance of getting published in today's climate, you need positive results on a novel enough experiment. And if you want to meet your publishing quota, you need to do most of the work all by yourself. That's the real reason why micro- and nanofluidics are not taking off: it takes way too damn long to build enough devices to get to a workable experiment.
    I also concur: lab-on-a-chip is not happening anytime soon. The natural development path really is to have more and more chip-in-a-lab devices, which might one day be integrated into a lab-on-a-chip. But you need to prove and improve all the individual components before you can assemble them into a VLSI-like system.

    There's another lab-on-a-chip concept that involves more biological instead of physical/chemical interaction. Growing tiny tissue clusters and then subjecting them to specific treatment (medicines, bacteria, chemicals, etc) produces an observable output that can help accelerate and unblock several new therapies that are either too expensive or risky to trial on human subjects.

      Absolutely. A relative of mine works at an (actual) blood test company and they are very interested in solving this problem. But since Theranos, it's become incredibly hard to get funding for it, even if you try to solve it legitimately and have the track record to back up your claim of knowing how to develop and provide blood tests. Kinda sad because the technology has a lot of potential.

    • @roberthoople
      @roberthoople ปีที่แล้ว

      I'm not disagreeing with you, but I had never heard of Lab on a Chip - even while Theranos was advertising - until it blew up into a huge scandal that every news report covered.
      So, while it did some damage in the short term, it may have actually helped the industry long-term by bringing awareness of the technology to the general public. When I started looking into Theranos to see what the story was about, it was pretty apparent in most coverage that I read, in spite of the fraud by Holmes, that the science behind the technology was in fact valid and being pursued by some of the world's premiere research institutions. Now I try to keep tabs on the industry, excited for the next real breakthrough.

    The biggest issue with microfluidics in the diagnostics (DX) space, excluding the limited cases where they are already used, is that they don't really do anything BETTER than current technologies. Most current DX systems already handle essentially all of the sample prep, sample control, and specific tets run. The operator just checks the tube of blood, scans the barcode, and inserts it into the system. The system handles the rest, right down to uploading the results.
    Microfluidics emphasizes the concept of multiplexing tests, but there is little to no value in running unnecessary tests. An assay that runs 100 different tests when only two are needed is only worth those two tests; the other 98 are just wasted costs. Most modern DX systems will multiplex a handful (up to a dozen or so) of tests together which would logically be run together (e.g.multiplexing IgG, IgM, and Antigen tests for a particular infection). There are only so many tests that can be logically grouped together.
    Lastly, for some DX tests, the usable concentration of analytes is so low that you can run into issues with minimum sample volume. This is especially true if a quantitative or semi-quantitative result is desired, rather than a simple binary result.

      That reminds me of how most of the successful commercial development in the parallel computing space so far has been in single instruction multiple data (SIMD) processors, rather than multiple instruction single data (MISD). The former performs the same operation on a hundred samples simultaneously, while the latter performs a hundred different operations on the same sample. Most of the time, the former is more useful.

      "Better" comes in a lot of ways.
      The lab on chip is dirt cheap compared to big machines.
      They also require no specially trained people to go around fixing and calibrating. No one going around cleaning and sterilizing.
      Then there's the drastic reduction in electricity needed to run tests.
      And let's keep in mind that if you have a box of 500 loc's, you can have 500 people being tested at once.

    We have that iStat device at my hospital. It is useful but I wouldn't call it "lab quality," it's mainly helpful for giving us an approximate answer very quickly e.g. when we have someone come in who might be in diabetic ketoacidosis and we want to do a blood chemistry. We still pretty much always send blood to the regular lab for definitive results.

    • @syjiang

      I'm uncomfortable with manufacturer's claims of "Lab Quality". They muddy the water on these issue and it is interesting Abbot's i-Stat product webpage plaster a warning to me "BASED ON YOUR CURRENT LOCATION, THE CONTENT ON THIS PAGE MAY NOT BE RELEVANT FOR YOUR COUNTRY." Which probably meant Health Canada called their bullshit and restricted their approved labeling for medical device. I'm reasonably confident that their equipment can do a good job of accurate measurement ...but what is the quality of what they are measuring? I am not confident that a few drops of whole blood can be reliably reflect the actual intravenous status of patient. A pointless test given the sample limitation IMO, hope they put more money into speeding up and reducing the cost of actual lab testing.

  • @kanzi1958

    I'm a strong believer in the "KISS" principle: keep it simple, stupid. The problem in today's academia is that researcher's main task is to get published, and get published in the most prestigious journal, if at all possible. As a result, they are too often compelled to do "hero" experiments, that are extremely complex, and require multi-million dollar labs full of the latest equipment. When it comes to transferring that to a commercial product that is low cost and easy to mass produce, they are completely clueless. They are just not trained to think about those things. Successful commercial products generally adhere to the KISS principle. The glucose test does one thing, and one thing only. I'm currently working on a (very) low-cost, optical fiber sensing technology. The couple of papers I've published have attracted next to zero attention, and I'm not surprised, and yet I can get 100 times better resolution than all other papers in the field, at a 1000x smaller cost, but talking about cost in an academic paper is a big taboo. You can talk about "potentially" low cost, but an actual low cost, high performance device won't get you published in Nature Photonics, because there is no "big science" in it. Making things simpler is just not considered "advanced" science. This, despite the fact that technologies such as the IC started off as very simple devices. In fact, it is their simplicity, compared with bulk circuits, that made them so successful. Complexity was added later, but only because the process was, at its core, very simple. If the technology is complex and difficult to start with, it will never make it commercially because you can never get to mass production and high yields. So I think microfluidics is suffering from that disease. I've followed the field for 20 years, and considered using the technology, but it is actually very complex. I will stick to my little fiber optic sensors: easy to make, easy to mass produce, and extremely low cost due to all the cost reduction brought about by the massive deployment of optical fibers in the past 40 years. But I can tell you, convincing investors about it is THE most difficult thing in the world. They'd rather go with a fancy AI app. One more.

    I worked in years for microfluidics (under dr Ramsey and Henly- check the lit they’re big guys) I was an undergrad at the time so no papers for me. I don’t really think this is more than a dead end frankly. I tried so hard to solve a few problems. There are some surprising issues that make this much harder than you think.
    Though it’s fascinating. I’m sure some of the early IC guys lost faith too. So take my opinion with a grain of salt. I worked on 2 phase separation - the first separated on hydrophobic proteins vs drag then injected into another CE separation where it separated based on charge vs drag.
    The big problem is the mixing problem and the non-orthogonal nature of those two methods.
    And it is surely not “self powered”
    We ran 10kV through it. In other words a crap ton. Small currents. But you require the voltage to create the electro-osmotic flow. The glass (borosilicate) becomes all negative charged because that’s what borosilicate does. Then the water being a dipole lines up the positive part to interact with the walls, all the positive outside water molecules run to ground . Because they are all the outside water in the “channel” they drag the rest of the water with mass flow.
    So the channels have to be small.
    We separated proteins from single cells. Normally if you do genetics on a biopsy you are analyzing the genetics of ALL the cells which are all doing different things.
    Doing a single cell let’s you see what one cell is doing.
    We also did DNA sequencing, by passing dna through a small pore and reading the resistance as it passes through one at a time. DNA has a negative charge so you can do this.
    But clogging.
    Dear god clogging . 95% of my time was Declogging my chips. It took days to make a batch of chips
    By hand buy using old photolithography methods.
    If one clogged, which happened all the f-Ing time it could take days and days and days to unclog.
    Maybe it was dust. Maybe some of the salt came out of solution in your buffer solution, you would stare under a microscope for hours and hours and pass solvents through the channel to try and dissolve the clog and it never freaking worked

    • @altimmons
      @altimmons ปีที่แล้ว

      I’d be happy to have my “paper” (honors thesis) that explains things at a much lower lever since I started from fundamentals and worked
      My way up. Mostly because I had a lot of pages to fill, wanted to show I understood the science, and the post doc assigned me a problem he couldn’t solve which was sorta a jerk move. So my “paper” had no “nove” findings and useless for anything other than the honors on
      My degree. Anything I tried he’d condescendingly say I tried that. So I would scour research looking for ideas and I’m convinced the problem isn’t solvable on the purest sense. Smaller gate channels might help but then you run into lithography errors cutting such narrow channels and even more clogging. If only it didn’t take weeks to make more chips.

    Great video about an interesting topic, as usual :)
    At first glance, deterministic lateral displacement can be easily explained by fluid dynamics, or just make an experiment yourself:
    On a stormy day, try to shield yourself from the wind by standing behind an advertising pillar - or any large, perpendicular, cylindrical object at your disposal. You will find, that the wind speed behind that object is in fact larger than the wind speed blowing at its front.
    Due to Bernoullis law, an increase in speed of a fluid results in a decrease in static pressure. An object subjected to different levels of pressure experiences a force towards the lower pressure zone (think of buyoyanci).
    The magnitude of that force is determined by the size of the area affected, therefore large particles experience a stronger force than smaller ones (assuming spheric particles, this factors in with radius squared)
    But the inertia of the particles counteracts this force. The inertia factors in with radius to the third power, therefore the resulting acceleration of smaller particles towards the zone of lower pressure is larger than that of larger particles, assuming their density being similar.

    @Asianometry i have a question and i would appreciate your answer. Do you research about the subjects you make videos(sepetially the ones on tech stuff) or is it part your field of study, and if it is the latter and if you dont mind whats ur field of study/research/work, because u seem well rounded in many topics(espetially microships, but also material sciences ,optics, pharma, tech, ai.. and even economics) but you also able to post frequently which i suppose leave you with little time to possibly research ur videos ?

    Thanks, this is a good review of the field. As a researcher in this field, I can say that the technology to miniaturize regular tests is there but the big question is economics. This is especially important when i-Stat already offers a lot of these advantages. Instead of making lab-on-a-chip, microfluidics will evolve to process biological samples which are erstwhile hard to process or result in poor yield by conventional bench-top technology.

    We are growing organoid in the chips and the major breakthrough was when the 3D printers got sufficient resolution to be able to print the molds (200um features). Otherwise there is absolutely zero tasks for microfluidics which can’t be done on the multiwell plates.

    Might be expensive but spamming sensors and chips distributed to up the scale of required data sets to monitor the entire human body (or anyliving entity)? Having a larger compute with AI overstructure can organize these sub structures like a broodmother with a swarm of sensors/SoC's in a body?

    We have a NanoOne 3D printer to custom make chips in our lab, the integration to the rest of the processes is super simple since the new chips have pumps and sensors integrated and all connectors are printed instead of glued on !
    Just like MEMS packaging it solves the integration for us.

    For classic organic synthesis this method gives high yields. Compare it to a bulk method...every molecule have to shake hands inside a big hall, but if you restrict them to a hall-way, it gets easier.. aka higher yields

  • @fritzx735
    @fritzx735 ปีที่แล้ว +2

    It think that a lot of people including you look on this topic from the wrong perspective.
    If there are chemical tasks to be done then the (main) functionality does not lay in the chip itself but of course the chemicals used and this is the area where research has to go into and not the chip itself that is just performing supportive and/or protecting tasks. This is the case because as you rightfully point out a lot of tasks in both detection and especially in preperation just cant be provided with a chip and need a lab anyway. The only way to work around this is developing analytical chemicals that perform these tasks since they are the only part here that can be scaled down with no differences/ loss in functionality.
    But since investors, politicans etc. just see the word "chip" and ignore the "lab" part ...
    theres yet much time needed I guess.

    Possibly, it would be worthwhile to have one chip to perform all of the tests that are now performed on different chips. A single fab is less expensive than several even when it fabricates a more complex chip.

    Microfluidics was used for high throughput RT-PCR testing for SARS-CoV-2/COVID-19. I think it worked well in this case because there was a need for large batches of a single test. Far from a lab on a chip, but there have been some practical applications.

    There's a bigger reason these don't work out so well - after you've placed all these super sensitive structures and devices on a wafer....how do you dice the darn thing without applying chemicals or water that'll break or clog the device? This is where Stealth Dicing holds a big edge on other methods - without the need for chemicals like ablation lasers or plasma, nor the water jet and vibration of a blade saw, the NIR-Laser's use of creating internal cracks within the silicon has been an important step in helping that industry. I worked with such "lab on a chip" concept, but it had problems - the NIR can't function through metals, and since most traditional schematic to layout designers placed PCM's and other test structures along the dicing lane with the assumption they'd just use a blade saw, their miracle on a chip turned into a nightmare, and the most awkward five minute teams meeting meltdown I've ever seen, as their senior engineer just screamed **** repeatedly and started crying... There would be no "remasking" - this was supposed to be it, and they'd blown all their money on prototypes that hadn't foreseen the backend issues, and now they had the world's most sophisticated lab-on-a-chip, but no one in the world could properly(and cleanly) singulate the darn thing.

      Apparently because the economics of chip fabrication - It's cheaper to produce ten million chips that does a hundred tests than it is to produce thousands to a million chips for each of a hundred different tests. The first chip of a new product is insanely expensive, but if you produce enough the price drops through the floor.
