What Are the Recent Advancements in Visualization Techniques?
Recent advancements have significantly improved the capabilities of visualization techniques in nanotechnology:
1. Cryo-Electron Microscopy (Cryo-EM): This technique involves freezing samples at cryogenic temperatures to preserve their native state. Cryo-EM has revolutionized structural biology by enabling the visualization of biomolecules at atomic resolution.
2. Super-Resolution Microscopy: Techniques like STORM and PALM have broken the diffraction limit of light, allowing for imaging at resolutions previously thought impossible with traditional optical microscopy.
3. Correlative Light and Electron Microscopy (CLEM): CLEM combines the strengths of light and electron microscopy to provide complementary information about the same sample, offering a more comprehensive understanding of the material.
4. Quantum Dots: These are semiconductor nanocrystals that can be used as fluorescent probes for high-resolution imaging in biological systems.
