    Really informative. Thank you. Several companies are now making commercial quantum dots. Besides using dot size to modify the emission wavelength, it's also possible to tune the output wavelength using a composition gradient in the core material.

    I actually made CdSe QD synthesis optimization as a project yet with the TOP/TOPO method. Also made multishells. Thing is I didn't have to evacuate the vessel that long. The basic synthesis is really this easy though time-consuming due to the purification steps if you're doing multshells. Too bad I didn't have time to do biofunctionalization.

    @espydude Typically Quantum dots are very useful for research purposes. Its hard to get enough dots to the cancer cells in a living person to be visible, and they can potentially have harmful effects. There is some research to try to do this, but for the most part dots are a research tool currently.

    • @jameszhang9326
      @jameszhang9326 4 ปีที่แล้ว

      Not that simple to answer. Depends on the bonding affinity+type and the specific region that you're trying to dye-mark.

  • @OfficeThug

    Man, I could probably make this stuff in my own lab. We have 2 gloveboxes, 8 schlenk lines and about 10 different distillation columns. Unfortunately our group only works with organic flow-cell battery materials and super organic reducing agents. Our stuff is either lovely black, lovely goop, or extra-lovely tar like substance that spontaneously combusts in air.

    @61324852 @61324852 More than likely you'd use the SILAR method for covering the QD with an epitaxial inorganic layer that has a wider bandgap (for coating CdSe you'd use something like CdS, ZnS) see Peng et al, 2003 Large-scale synthesis of nearly monodisperse CdSe/CdS core/shell nanocrystals using air-stable reagents via successive ion layer adsorption and reaction
    As for who invented QDs, the modern incarnation of what she's working with is attributed to Bawandi and Murray ~ 1993

    Is this actually the process to identity cancer cells? Or just a study lab? I'm wondering because it seems most of this could be optimized to provide a streamlined analysis of cancer cells.

      I don't know how prevalent this method is today, but doctors have been able to identify cancer cells a long time before QD was invented.
