Optical fiber sensors based on tapered optical fiber (TOF) structure have attracted a considerable amount of attention from researchers due to the advantages of simple fabrication, high stability, and diverse structures, and have great potential for applications in many fields such as physics, chemistry, and biology. Compared with conventional optical fibers, TOF with their unique structural characteristics significantly improves the sensitivity and response speed of fiber-optic sensors and broadens the application range. This review presents an overview of the latest research status and characteristics of fiber-optic sensors and TOF sensors. Then, the working principle of TOF sensors, fabrication schemes of TOF structures, novel TOF structures in recent years, and the growing emerging application areas are described. Finally, the development trends and challenges of TOF sensors are prospected. The objective of this review is to convey novel perspectives and strategies for the performance optimization and design of TOF sensors based on fiber-optic sensing technologies.

“…To date, several analytical techniques have been developed and applied for the determination of Cu 2+ and thiram residues, including GC-MS (Gas chromatography-mass spectrometry) and spectrophotometry, SPR (surface plasmon resonance) [8], colorimetry [9], SERS (surface-enhanced raman scatting) [10], and electrochemistry [11]. However, these methods are often time-consuming, cumbersome and require tedious sample pretreatment in the applications of water quality and food safety analysis.…”

Food contaminants pose a danger to human health, but rapid, sensitive and reliable food safety detection methods can offer a solution to this problem. In this study, an optical fiber ratiometric fluorescence sensing system based on carbon dots (CDs) and o-phenylenediamine (OPD) was constructed. The ratiometric fluorescence response of Cu2+ and thiram was carried out by the fluorescence resonance energy transfer (FRET) between CDs and 2,3−diaminophenazine (ox-OPD, oxidized state o-phenylenediamine). The oxidation of OPD by Cu2+ resulted in the formation of ox-OPD, which quenched the fluorescence of CDs and exhibited a new emission peak at 573 nm. The formation of a [dithiocarbamate-Cu2+] (DTC-Cu2+) complex by reacting thiram with Cu2+, inhibits the OPD oxidation reaction triggered by Cu2+, thus turning off the fluorescence signal of OPD-Cu2+. The as-established detection system presented excellent sensitivity and selectivity for the detection of Cu2+ and thiram in the ranges of 1 ∼ 100 μM and 5 ∼ 50 μM, respectively. The lowest detection limits were 0.392 μM for Cu2+ and 0.522 μM for thiram. Furthermore, actual sample analysis indicated that the sensor had the potential for Cu2+ and thiram assays in real sample analysis.
