Biophotonics is an emerging multidisciplinary research area, embracing all light-based technologies applied to the life sciences and medicine. Biophotonics is a scientific discipline of remarkable societal importance. For hundreds of years, researchers have utilized light-based systems to explore the biological basics of life.
Diagnostic biophotonics is used to detect diseases in their initial stages before actual medical symptoms occur in patients. By using optics, diagnostic biophotonics provides several advantages of sensing and imaging at the molecular level and also collects multidimensional data for evaluation. Technologies based on light are generally contact-free with less effect on integrity of living subjects and, consequently, can easily be applied in situ.
Applications of light include treatment of diseases by altering biological processes. Light is used for modifying the cellular functions photochemically and to remove tissues by photomechanical or photothermal process.
