Researchers at Washington University have genetically-engineered cells to react to light.
By taking light-sensing receptors from the eye — called opsins — and inserting them into immune cells, the researchers were able to trick the cells into moving toward a laser beam, in the same way they would move toward a bacterial infection.
Washington University molecular biologist N. Gautam led the research.
