Optical tweezers use laser light to manipulate small particles. A new method has been advanced using Stampede2 supercomputer simulations that makes optical tweezers safer to use for potential biological applications, such as cancer therapy. (a) Image shows schematic of red blood cells in solution. (b) Timelapse showing trapping and thermal rupture at ambient temperature. (c) Timelapse of trapping using new method. No cell rupture is observed. Credit: Nature Communications (2023). DOI: 10.1038/s41467-023-40865-y
Optical tweezers manipulate tiny things like cells and nanoparticles using lasers. While they might sound like tractor beams from science fiction, the fact is their development garnered scientists a Nobel Prize in 2018.
Scientists have now used supercomputers to make optica...
