Switching on the activity of drugs with infrared light - technology short science news

Scientists have developed a new technique that makes it possible to activate a molecule that is already in the body by light.

Shining light locally is thought to limit unwanted side effects of the molecule, which is important for medical use.

This new technique has been developed in worms and is an important step forward to full control of when and where medication should become active in the body.
