Stanford University Research Team Designs New Microscope That Can Track Motion of a Single Protein With Atomic Level Precision
The university scientists have created an innovative device that uses infrared light to trap and control the forces on a functional protein, allowing researchers to monitor the molecule's every move in real time. The microscope achieves these results through an ultra-stable optical trapping system with angstrom resolution. This breakthrough allows scientists to better understand enzyme action and paves the way for new discoveries about the molecular machinery that carry out fundamental cellular processes, such as the way genes are copied from DNA. The research team notes this instrument took years of R&D, funding from both the National Institutes of Health (NIH) and the construction of a special laboratory by Stanford.
