A new look at optical tweezers
Abstract:
Optical tweezers are a small but important tool in biophysics, nanotechnology, and molecular biology labs. They have been used to examine the amount of force it takes to stretch and twist individual DNA molecules, study Brownian motion, and manipulate cells, to give just a few examples. As with all applied research, optical tweezers—outside of the context of trapping and/or cooling atoms—has been rather quiet for the last few years because the technology was "good enough." However, as with all of these things, a revisit is often warranted because a field that looks dead is often revived by developments from other research areas.
