The act or process of inducing photosensitivity.
photosensitize pho·to·sen·si·tize (fō'tō-sěn'sĭ-tīz')
v. pho·to·sen·si·tized, pho·to·sen·si·tiz·ing, pho·to·sen·si·tiz·es
To make an organism, a cell, or a substance photosensitive.
the process of initiating a reaction through the use of a substance capable of absorbing light and transferring the energy to the desired reactants. The technique is commonly employed in photochemical work, particularly for reactions requiring light sources of certain wavelengths that are not readily available. A commonly used sensitizer is mercury, which absorbs radiation at 1849 and 2537 angstroms; these are the wavelengths of light produced in high-intensity mercury lamps. Also used as sensitizers are cadmium; some of the noble gases, particularly xenon; zinc; benzophenone; and a large number of organic dyes.
