About Biophotonics

Biophotonics is a multidisciplinary field that studies the interactions between photons—the quantum units of light—and biological systems.  Basic research can be broadly applied, but medical applications are of particular interest, as an aging population and projected economic and demographic changes in industrialized and third-world countries demand the development of cheap and lightweight medical solutions, particularly those that are non-invasive and can be used without the supervision of a physician or other medical professional.
