British scientists have unveiled a glowing bandage that not only treats wounds but destroys skin cancer cells with light.
A flexible strip of plastic embedded with light-emitting diodes focuses a high-powered red light beam on tumors. When the light is absorbed by a special skin cream, cancer cells are killed.
The laser bandage allows patients to receive treatment without having to submit to hours of inactivity under lights in a clinic or hospital.
Polymertronics and Lumicure are two companies currently pursuing this general technology.
