Introduction to s-SNOM
Fritz Keilmann discusses advancements in microscopy, particularly focusing on the development of super-resolution microscopy techniques that exceed traditional limitations.
Key learning objectives from the talk:
- Understanding Super-Resolution Techniques: Learn about the principle behind super-resolution microscopy, specifically how methods like STED microscopy allow for imaging below the diffraction limit of light, providing greater detail in biological studies.
- Applications and Innovations in Microscopy: Understand recent innovations in microscopy, such as color nanoscopy and the use of metallic wave guides, and their applications in enhancing image resolution and simplifying the instrumentation.
- Future Directions and Practical Implementations: Gain insight into new, less expensive, and more accessible methods of super-resolution imaging, and explore the potential future applications in biological research and material science.
This video was recorded with the financial support of the Teaming for Excellence program (European Union Horizon 2020; GA 857543) during the Near-field Optical Nanoscopy Summer School (Donostia- San Sebastian; 6-9 June 2023) organized by neaspec/attocube AG, CIC nanoGUNE BRTA and the ENSEMBLE3 Centre of Excellence.
