Optical sensors are widely used for refractive index measurement in chemical, biomedical,
and food processing industries. Due to specific field distribution of the resonances, optical …

In the past few decades, glucose sensors have attracted continuous attention due to
demands in diabetes diagnosis, component analysis, biological detection and …

We propose and experimentally demonstrate a high-performance relative humidity (RH)
sensor by depositing graphene oxide (GO) onto tilted fiber grating (TFG). The largely tilted …

Fiber-optic evanescent wave (FOEW) sensors are promising in pollutant detection and
evaluation of water quality because of their high resistance to corrosion, smart structure, anti …

A label-free biosensor based on graphene oxide (GO) and glucose oxidase (GOD)
functionalized tilted fiber grating (TFG) with large tilted angle is proposed for low …

The aim of this paper is to provide a comprehensive review of mode-division and spatial-
division optical fiber sensors, mainly encompassing interferometers and advanced fiber …

Surface plasmon resonance (SPR) optical fiber sensors can be used as a cost-effective and
relatively simple-to-implement alternative to well established bulky prism configurations for …

Plasmonic immunosensors are usually made of a noble metal (in the form of a film or
nanoparticles) on which bioreceptors are grafted to sense analytes based on the …

The simple and highly sensitive measurement of the refractive index (RI) of liquids is critical
for designing the optical instruments and important in biochemical sensing applications …

Recently, human industrial practices and certain activities have caused the widespread
spread of emerging contaminants throughout the environmental matrix, even in trace …
