Biophotonics

Biophotonics is an interdisciplinary field focused on the effects and applications arising from the interaction of light with biological tissues. It bridges multiple domains including optics, optoelectronics, biology, medicine, and electronics, with applications spanning a broad spectrum—from biological research to medical diagnosis, therapy, and disease prevention.

01 Super-resolution imaging

Due to the diffraction of light, light emitted from a single point source forms a blurred spot (known as an Airy disk). When two point sources approach each other, they eventually reach a point where they can no longer be distinguished. This threshold, commonly referred to as the resolution limit, is typically around 200 nm. Super-resolution imaging techniques overcome this diffraction limit to achieve nanoscale resolution.

02 Tissue optics and spectral imaging

Tissue optics and spectral imaging investigate the principles of light interaction with biological tissues across different scales and physiological states, exploring the mechanisms underlying biomedical imaging. Building on this foundation, the field focuses on the principles and methods of optical diagnosis and phototherapy for major diseases, providing new approaches for early disease detection, treatment, and efficacy evaluation—ultimately serving clinical applications.

03 Bio-Optical Sensing and Modulation

Bio-Optical Sensing and Modulation enables the monitoring and regulation of biological structures and functions at the molecular level. It involves the detection of energy released in the form of photons from biological systems, monitoring the structural and functional information carried by these photons, and utilizing photons for processing and modifying biological systems. In medical research, this technology facilitates non-invasive disease detection, diagnosis, and treatment at both macroscopic and microscopic molecular scales.
