Scientists Create Laser “Whirlpools” That Spin Tiny Cells Without Touching Them

Researchers have developed a new laser-based method that can rotate microscopic samples in all three spatial directions without touching them. Until now, rotating extremely delicate microscopic samples in every direction without touching them has been a major technical challenge. Researchers at the Karlsruhe Institute of Technology (KIT) have now created a laser-based method that can [...]
