A new type of treatment called "light-activated drug delivery" is showing promise as a way to give doctors control over precisely where and when drugs are delivered inside the patient's body. Now, researchers have developed a light-activated way to target cancer cells without hurting healthy tissue by using drug-carrying nanoparticles.
