Photothermal therapy is a treatment in which plasmonic nanoparticles are delivered to tumors either intravenously or intratumorally subsequent exposure of the tumor to near-infrared light, which penetrates tissue more deeply than other wavelengths of light, causes synchronized oscillation of the nanoparticles' conduction-band electrons that results in heat production. Photothermal therapy (ptt) refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer this approach is an extension of photodynamic therapy , in which a photosensitizer is excited with specific band light.
In general, photothermal therapy depends on the photosensitizers taken up by cancer cells to transfer light to heat, leading to photoablation of the cells and subsequent cell death therefore, photosensitizing agents are a key factor in photothermal therapy.
