A team has re-engineered immune cells with a light-activated switch that modulates protein function and cellular behavior. When exposed to blue light, the cells change shape, infiltrating solid tumors ...

Vials held upright in a container with a grid of openings are on a lab bench and illuminated by a blue lamp. Many organic-synthesis labs have access to blue lights for photochemical reactions.

Light can be used to activate drugs in specific parts of the body through photopharmacology. This innovative approach involves modifying the chemical structure of a drug by adding a light-activated ...
