“…In 2019, Saurabh Mani Tripathi's research group designed a dual‐resonance LPFG‐based sensor for microcystin‐LR (MC‐LR) detection. [ 104 ] The aptamer covalently immobilized on the dual‐resonance LPFG acted as the recognition element of MC‐LR, which specifically captured MC‐LR and led to the resonance wavelength to shift.…”

Optical fiber biochemical sensing technology, as a cutting‐edge, multidisciplinary, and universal sensing technology, is gradually becoming the research focus in the field of biochemical sensing. They enjoy distinctive characteristics such as high cost‐effectiveness, flexibility, resistance to electromagnetic interference, and small size and can be used to detect biochemical analytes at ultra‐low concentrations with ultra‐low sample consumption, even when these biochemical analytes are in hard‐to‐reach environments. An aptamer is a DNA or RNA oligonucleotide fragment with a high affinity for the target selected from random sequences. Due to their advantages of simple synthesis, low cost, good stability, good specificity, and strong affinity, they are gradually becoming ideal recognition elements and may replace antibodies as next‐generation target receptors. Therefore, aptamers, as functional materials, are integrated into optical fiber sensors, which are called optical fiber aptasensors, providing new opportunities for the construction of high‐performance and intelligent biochemical sensors. This article aims to review the recent research progress of fiber‐optic aptamer biochemical sensors, with a focus on their sensing mechanisms and applications. Finally, based on the existing deficiencies of fiber‐optic aptamer biochemical sensors and practical requirements, their future development trends are briefly discussed.

Fiber optical refractometers have gained a substantial reputation in biological and chemical sensing domain regarding their label-free and remote-operation working mode. However, the practical breakthrough of the fiber optical bio/chemosensor is impeded by a lack of reconfigurability as well as the explicitness of the determination between bulk and surface refractive indices. In this letter, we further implement the highly flexible and reproducible long period grating called “VIOLIN” in chemical sensing area for the demonstration of moving those obstacles. In this configuration, the liquid is not only leveraged as the chemical carrier but also the periodic modulation of the optical fiber to facilitate the resonant signal. The thiol compound that is adsorbed by the fluidic substrate can be transduced to the pure alteration of the bulk refractive index of the liquid, which can be sensitively perceived by the resonant drift. Taking advantage of its freely dismantled feature, the VIOLIN sensor enables flexible reproduction and high throughput detection, yielding a new vision to the fiber optic biochemical sensing field.
