cryo-SEM

Cryo-SEM, or cryogenic scanning electron microscopy, is a sophisticated imaging technique used to observe biological and material samples at very low temperatures. By freezing samples quickly with liquid nitrogen or other coolants, it preserves their natural structure and prevents dehydration. This allows scientists to examine them under an electron microscope without damaging their integrity. The high-resolution images produced help researchers study details at the microscopic level, making it invaluable in fields like biology, materials science, and medicine for understanding complex structures and compositions.
