Optical Traps Illuminate the Subcellular World

Facebook X LinkedIn Email
Improved spatial resolution enables the study of biological systems on the nanometer scale.

Lauren I. Rugani, Contributing Editor

Optical trapping has been utilized in endeavors as varied as microfabrication, particle sorting and the study of nonequilibrium thermodynamics. The technique, also known as optical tweezing, is particularly beneficial for studies on the cellular level because it can isolate a system of interest from its environment, and it provides a noninvasive, nondamaging method for analysis. Continuous innovation and instrument refinement have overcome many challenges in the field of optical trapping, allowing investigators to study the smallest biological systems that operate within a cell....Read full article
