Photothermal therapy
Photothermal therapy (pronounced: fo-toe-thermal therapy) is a type of cancer treatment that uses light and heat to destroy cancer cells.
Etymology
The term "photothermal therapy" is derived from the Greek words "photo" meaning light, and "thermal" meaning heat.
Overview
Photothermal therapy is a minimally invasive treatment that uses nanoparticles to convert light into heat. These nanoparticles are injected into the body and accumulate in the tumor. When the tumor is exposed to a specific wavelength of light, the nanoparticles absorb the light and convert it into heat, which destroys the cancer cells.
Procedure
The procedure for photothermal therapy involves several steps. First, the nanoparticles are prepared and injected into the body. These nanoparticles are usually made of gold or other materials that can absorb light and convert it into heat. Once the nanoparticles have accumulated in the tumor, a light source is used to illuminate the tumor. The light is absorbed by the nanoparticles, which heat up and destroy the cancer cells.
