==== Optical tweezers ====
[[Optical tweezers]] (or traps) are scientific tools employed to maneuver microscopic particles such as atoms, DNA, bacteria, viruses, and other types of nanoparticles. They use the light's momentum to exert small forces on a sample. This technique allows for the organizing and sorting of cells, the tracking of the movement of bacteria, and the changing of cell structure<ref>{{Cite web|url=https://blocklab.stanford.edu/optical_tweezers.html|title=Block lab - Optical tweezers|website=blocklab.stanford.edu|access-date=2017-12-05}}</ref>
