Photoinduction refers to the process of inducing or stimulating a chemical reaction or a biological response with the use of light. Some synonyms for photoinduction include photostimulation, light-activated induction, photoactivation, and light-induced excitation. Photobiomodulation and photodynamic therapy also fall under the category of photoinduction, where light is used to activate or trigger cellular functions or to treat certain medical conditions. The use of photoinduction has wide-ranging applications in the fields of science, medicine, and technology, such as in the development of photovoltaic cells, optical storage devices, and targeted drug delivery systems. In summary, photoinduction is a versatile technique that allows for controlled manipulation of chemical and biological systems with light.
