The majority of biology and chemistry takes place in solution, in which temperature and refractive index sensing underlie molecular detection and profiling. All-in-fiber integrated devices are uniquely suited to detect the properties of samples.

Ultra-sensitive boric acid detection using a plasmonic fiber-optic spectral comb and MEA modified with gold nanoparticles

Even trace amounts of boric acid (BA) could cause serious harm to human beings and the environment. Therefore, trace BA detection is very important. Here, we propose a tilted fiber Bragg grating (TFBG)-based plasmonic fiber-optic spectral comb for ultra-low limit BA detection. The TFBG is coated with a gold film to excite the surface plasmon resonance (SPR) effect, and mercaptoethylamine (MEA) molecules are self-assembled and fixed on the gold film to form a BA probe.
