RESEARCH ON, IDENTIFICATION OF AND SCREENING FOR BIOLOGICAL MATERIALS USING LOW ENERGY ELECTRON MICROSCOPY

摘要

Described herein is a system and method for conducting research on and/or screening for viruses, capsids, antibodies, prions, proteins and DNA using a low energy electron microscope (LEEM). In some implementations, the system takes images of a biological sample, extracts information (e.g., size or shape of contents) from the taken images, and determines the presence or absence of biological agents, such as viruses, capsids, antibodies, prions, proteins and DNA, based on the extracted information. In some implementations, the system observes, identifies, and/or detects interactions between antibodies and viruses or other microbes, capsids, antibodies, prions, proteins and DNA, such as the binding of the antibodies to its cognate ligand. In some implementations, the system screens biological samples, based on detected interactions with known antibodies, to determine whether a person should be granted access to a controlled, restricted or protected location.
