A class of synthetic dyes, already used to bind to and highlight cancer cells, can be made to vibrate on exposure to near infrared light. The vibration destroys the cancer cell to which the dye molecules are attached. Tested on mice with skin cancer, perhaps some potential in other cancers depending on how far near-infrared penetrates. This is the first I’ve heard of a non-surgical mechanical approach to destroying cancer cells.
