What are Some Recent Advances in Image Acquisition Techniques?
Recent advances in image acquisition techniques have significantly enhanced capabilities in nanotechnology:
- Cryo-Electron Microscopy (Cryo-EM): This technique allows for imaging biological specimens in their native state without the need for staining or fixing, providing near-atomic resolution.
- Super-Resolution Microscopy: Techniques like STED (Stimulated Emission Depletion) and PALM (Photo-Activated Localization Microscopy) have broken the diffraction limit of light, enabling visualization of structures at the nanometer scale.
- Correlative Microscopy: Combining different imaging techniques, such as SEM and AFM, allows for comprehensive analysis of nanostructures by leveraging the strengths of each method.
