Electron Microscopy
Electron Microscopy — An imaging technique using electron beams to visualize structures at nanometer resolution, applied to study peptide self-assembly and nanostructures.
What Is Electron Microscopy?
Electron microscopy (EM) uses electron beams instead of light to image structures at nanometer to angstrom resolution. In peptide research, EM visualizes peptide self-assembled nanostructures (fibers, micelles, vesicles), amyloid fibrils, and peptide-nanoparticle complexes. Cryo-EM determines atomic-resolution peptide-receptor structures.
Types
- TEM: Transmission EM. 2D projection images. Negative staining or cryo preparation
- SEM: Scanning EM. 3D surface topology of peptide materials and scaffolds
- Cryo-EM: Flash-frozen specimens. 2-4 Å resolution for single-particle analysis
