“Researchers from BioForce Nanosciences Inc., Iowa State University, and Des Moines University have combined an atomic force microscope with a method of capturing virus particles to produce a tool that rapidly detects viruses.
The atomic force microscopy immunocapture assay consists of a chip, dubbed the ViriChip, that contains antibody molecules used to selectively capture viruses. An atomic force microscope is then used to analyze what has been trapped. Atomic force microscopes use nanoscale tips to trace the topography of surfaces and are capable of detecting individual atoms.”
