Applications and progress of nanofilm-modified long period fiber grating in biological and chemical analysis

Abstract

This review focuses on the nanofilm-modified Long Period Fiber Grating( LPFG) and makes a brief presentation for progress of its applications in refractive index biosensor. The influence of nanomembranes on refractive index sensing performance of LPFG is elaborated. Furthermore,applications of nanofilm-modified LPFG in the field of biological and chemical analysis are discussed in detail. At last,the further development and application of nanofilm-modified LPFG refractive index sensor are prospected.
