2021-06-27 20:37 Scanning electron microscopy (SEM) is characterized by simple sample preparation, wide adjustable magnification range, high image resolution, and large depth of field. SEM technology can scan the surface morphology of the sample by emitting a bright focused electron beam. The electron beam interacts with the appearance of the sample surface to generate a variety of signals that can be detected. These signals include the surface morphology and composition of the sample. Creative Biostructure provides SEM services for the characterization and research of coronavirus and coronavirus-like particles.
