In-Situ Characterizations of Supramolecular Structures through Cryogenic Transmission Electron Microscopy (Cryo-TEM)
Self-assembly is a type of process in which a disordered system of pre-existing components forms an organized structure or pattern as a consequence of specific, local interactions among the components themselves, without external direction. Meanwhile, degree of ordered molecular arrangements has a significant effect on the properties of resultant materials. Many nanomaterials are prepared in solution with template methods and it remains as a great challenge to conduct in-situ characterizations of intermediate micro/nanostructures during the process of self-assembly, though we can observe the assembled structures with conventional electron microscopy. Cryo-TEM can fix and maintain the nanostructures by physical cooling and then perform in-situ TEM measurements at an ultra-low temperature. In addition, Cryo-TEM is also an important method to study the assembled structures and mechanisms during the self-assembly process.
Since 2001, we have made a series of innovations in characterizing the in-situ nanostructures with Cryo-TEM, which are highly evaluated by the international counterparts.
