Abstract

Optical fiber sensors show a huge potential in biomedical and biosensing applications. Distributing sensing combined to scattering level spatial multiplexing techniques permits a large amount of sensing points in small area or volume, often mandatory in biomedical field. Moreover, the capability of micro-fabricating the optical fiber, enlarge the possibility to sense refractive index and, with the proper functionalization, the fiber can become a powerful, sensitive, and inexpensive platform for Biosensing. Here we aim to depict a brief perspective and illustrate future development of optical fiber sensors in biosensing and biomedical areas.
