TL;DR: The proposed ultrasensitive biosensor demonstrates an ultrahigh sensitivity with limit of detection of 7ng/mL, which is 10-fold better than non-coated dLPG biosensor and 100-fold greater than LPG-based immunosensor.

TL;DR: In this article, a graphene oxide (GO) nanosheets functionalized long period grating (LPG) was used for ultrasound hemoglobin sensing, based on the measurement of LPG resonant intensity change induced by the adsorption of hemoglobin molecules onto GO, where GO as a bio-interface linkage provides the significant light-matter interaction between evanescent field and target molecules.

TL;DR: The first black phosphorus - fiber optic biosensor for ultrasensitive diagnosis of human neuron-specific enolase (NSE) cancer biomarkers is proposed and it is believed that BP-fiber optic configuration opens a new bio-nano-photonic platform for the applications in healthcare, biomedical, food safety and environmental monitoring.

TL;DR: In this paper, an integrated black phosphorus (BP)-tilted fiber grating (TFG) configuration was proposed as an enhanced light-matter interaction platform for heavy metal chemical sensing, which secured high-quality BP coating on specific fiber cylindrical surface with strong adhesion as well as a prospective thickness control.

TL;DR: The proposed one-step EDC reaction approach can be further extended to develop fiber optic biosensors for disease analysis and medical diagnosis with the advances of label-free, real-time, multiplex, high sensitivity and specificity.
