Microrotors Trap Tiny Objects Without Exposing Them to Light
EXETER, England, March 18, 2019 — A team of researchers from the Universities of Glasgow, Bristol, and Exeter have developed a technique that optically traps microscopic objects by using hydrodynamic forces to exert nanoscale-precision control over aqueous particles, without directly illuminating them. This novel approach could lead to optical tweezers that will be able to trap and manipulate complex objects without exposing them to the risks of high-intensity light. The researchers used light-driven microrobotics to move
