Biophotonics is revolutionizing the field of medicine, biology and chemistry and creating a new breed of medical engineers while at the same time getting engineers a taste of medicine. From an engineer's perspective, biophotonics is the application of photonics - the technology of generating and harnessing packet of light energy called photons - to image, detect and manipulate biological materials. In biology the understanding of molecular mechanisms, function of proteins and molecules has seen great new advances. In biomedical engineering detection, diagnoses and treatment targeting both macro-objects like the teeth or bone as well as micro-objects such as bacteria have seen better understanding through the development of new tools.
