The combination of 2D materials and optical biosensors has become a hot research topic in
recent years. Graphene, transition metal dichalcogenides, black phosphorus, MXenes, and …

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 …

Graphene and related two-dimensional materials have attracted great research interests
due to prominently optical and electrical properties and flexibility in integration with versatile …

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 …

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 …

We propose the first black phosphorus (BP)–fiber optic biosensor for ultrasensitive diagnosis
of human neuron-specific enolase (NSE) cancer biomarkers. A novel optical-nano …

We report the sub-parts-per-billion (sub-ppb) level detection of lead using black phosphorus
(BP) integrated tilted fiber grating (BP-TFG) configuration where the light-matter interaction is …

The tilted fiber grating (TFG) is a special grating whose grating planes are slanted or blazed
relative to the fiber axis. These tilts in the planes break the cylindrical symmetry of the fiber …

The development of excessively tilted fiber gratings (Ex-TFGs) provides a new type of
sensing device with high refractive index (RI) sensitivity, low thermal crosstalk and vector …

We created an all-fiber solution for fast, continuous, and controllable tuning of Fano-like
resonance. By embedding a graphene-coated fiber Bragg grating into one arm of a Mach …
