Abstract Transmission electron microscopy (TEM) offers unparalleled atomic-resolution imaging of complex materials and heterogeneous structures. However, high-energy electrons can induce structural damage, posing a challenge for electron-beam-sensitive materials. Cryogenic TEM (Cryo-TEM) has revolutionized biology, enabling the visualization biomolecules in their near-native states at unprecedented detail. The low dose stable cryogenic environment Cryo-TEM are now being harnessed investigation low-temperature quantum phenomena. Here, we present systematic review interaction mechanisms between atomic structures, illustrating beam-induced damage mitigating role Cryo-TEM.
