Biophotonics is a research field that combines biology and photonics – the study and manipulation of light. It involves the development and application of optical techniques and technologies to study biological processes and structures at the molecular, cellular, and tissue levels. Biophotonics is used in a variety of applications including imaging, sensing, diagnostics, and therapy in fields such as medicine, biology, and agriculture. This interdisciplinary field has the potential to revolutionize healthcare by offering non-invasive and label-free methods for detecting and treating diseases.
