Optical fibers are used in medicine and biology

Optical fibers are used in a wide range of applications in medicine and biology, ranging from optical ducts and pressure sensors to complex chemical sensors. Coherent fiber bundles can be used for endoscopic imaging, while single fibers can be used for near-infrared layered imaging and Optical coherence layered imaging.

The use of optical fibers can also facilitate the transmission of optical radiation into tissues to activate target chemotherapeutic drugs. The chemical sensing technology that uses planar optical fiber light guides to transmit light waves to the measurement site can perform photometric and fluorescence analysis. Optical fiber Chemical sensors also have surface molecular recognition sites or chemical reaction sites, which can be used for the detection of specific molecules. These chemical sensors are based on the principles of surface plasmon resonance, interference, spectrometry or fluorescence measurement. High specificity can be obtained. In recent years, the range of target molecules measured has been developed from simple gas molecules and ions to DNA, etc.
