A fiber optic sensor platform for smart hydrogel event detection

Hydrogel-integrated optical fiber sensors and their applications: a comprehensive review

“…84 The temperature change can affect the refractive index of the optical fiber sensors in which hydrogels are incorporated, which allows the optical fiber to be considered for various biological sensing applications. 88,89 2.5. Comparative discussion on hydrogels, aerogels, and xerogels Aerogels and xerogels are light solid materials with highly porous structures and surface areas constructed from the drying of gels.…”

“…160 The integration of hydrogel fibers can improve the optical sensing capabilities of MZI sensors, including an increase in the sensitivity of detection of changes such as the refractive index change. The general characterization of these sensing systems can be done by measuring the RI change, 161 the interference wavelength response, 88 or the optical transmission change, 89 which are caused by the mechanical change of the hydrogel medium. Hence, the characterization is done by simply detecting the spectral response of the MZI system.…”

Sensing enhancement of nanostructure surface plasmon resonance in optical fiber ring resonator

“…In the recent days much efforts have been done to discover lable-free, low-cost, rapid, detection of multiple sample in parallel, high sensitivities method for detection technology due to this importance and emergency in different fields of knowledge ranging from medical to photonic and chemical detection. Newly optical biosensors among all type of biosensors like, mechanical, electrochemical, calorimetric and acoustic have gained great attention owing to providing direct, high selectivity and sensitivity, real time, sample and cost-effective operation (Lim et al 2002;Seo et al 2020Seo et al , 2019Senosiain et al 2001). Generally, biosensors convert recognition signal to the electrical signal that depends on the concentration of analyte performs the identifications operation (Li et al 2017).…”

Study the Adsorption of Letrozole Drug on the Silicon Doped Graphdiyne Monolayer: a DFT Investigation

“…For many applications such as biosensors, chemical sensors, and catalysts, the recent developments in the carbonaceous material such as graphane, graphyne, and graphdiyne are the pioneers in the research field [29][30][31][32][33][34][35][36]. In addition, in recent years the detection of many different viruses was important for controlling disease spread [37][38][39][40][41]. According to molecular dynamics, Barraza-Lopez and Kaloni have been considered the water dissociation on the monolayer monochalcogenides of group IV, like phosphorene, GeS, GeTe, and GeSe [42][43][44][45][46][47].…”
