Biomedical photonics is an interdisciplinary research field that applies the principles and technologies of light (photons) to address problems in biology and medicine. It encompasses the study of light-tissue interaction, the development of optical methods for diagnostic imaging and sensing (e.g., spectroscopy, microscopy, tomography), and the application of light for therapeutic interventions (e.g., phototherapy, laser surgery), providing crucial tools for non-invasive analysis and treatment in healthcare and biological research.
