“…Furthermore, the electrode can be modified to enhance sensitivity and selectivity. 15,16 Thus, this MIP sensor offers selectivity and sensitivity, and is accurate for individual GLY 15 and PQ 16 analysis in food samples. However, despite its beneficial characteristics, the two remaining challenges are sensitivity enhancement for water-quality control and dual-imprinting of PQ and GLY for simultaneous determination.…”

“…Recently, molecularly imprinted polymers (MIPs) have gained attention as recognition elements for sensor development due to their high selectivity towards the target analyte and their advantages compared to biological/natural receptors: (i) cost-effectiveness and straightforwardness to synthesize, (ii) physical and chemical robustness at high temperature, pressure, and in low or high pH solutions, (iii) reusability, (iv) stability and (v) possibility for large scale production. 15–18 MIPs can be prepared in different shapes, such as monoliths, thin films, or nanoparticles, depending on the application. There are different polymerization strategies, including bulk imprinting and surface imprinting.…”

Facile detection of β-lactoglobulin is extraordinarily important for the management of the allergenic safety of cow’s milk and its dairy products. A sensitive electrochemical sensor based on a molecularly imprinted polymer-modified carbon electrode for the detection of β-lactoglobulin was successfully synthesized. This molecularly imprinted polymer was prepared using a hydrothermal method with choline chloride as a functional monomer, β-lactoglobulin as template molecule and ethylene glycol dimethacrylate as crosslinking agent. Then, the molecularly imprinted polymer was immobilized on polyethyleneimine (PEI)-reduced graphene oxide (rGO)-gold nanoclusters (Au-NCs) to improve the sensor’s selectivity for β-lactoglobulin. Under optimal experimental conditions, the designed sensor showed a good response to β-lactoglobulin, with a linear detection range between 10−9 and 10−4 mg/mL, and a detection limit of 10−9 mg/mL (S/N = 3). The developed electrochemical sensor showed a high correlation in the detection of β-lactoglobulin in four different milk samples from the market, indicating that the sensor can be used with actual sample.

In today's technological landscape, advancing methods for producing conductive membranes that simplify and streamline the development of advanced interface materials is crucial. This study introduces a versatile and innovative method for fabricating superhydrophilic, conductive nanofibrous membranes based on the in situ synthesis of polypyrrole nanoparticles on poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) electrospun fibers. The composite membranes morphologically exhibit a particle‐decorated nanofibrous configuration, with polypyrrole nanoparticles distributed along the individual fibers' surface. The nanoparticle‐nanofiber configuration shows distinctive properties; electrochemically, the electrospun mats demonstrate excellent inherent electrical conductivity, good cyclic and high electrochemical stability, and low resistance. Furthermore, the amphiphilic and superhydrophilic behavior, achieved through nanotopography, porosity and interactions between the intrinsically conductive polymer and the PVDF‐HFP fibers, enables efficient uptake of polar and nonpolar analytes. The membranes also demonstrate good in vitro cell viability of both murine and human fibroblasts. Given its efficient interaction with liquids and omnidirectional 360‐degree conductivity, this material emerges as an excellent candidate for use as a biocompatible, multifunctional interface layer. The produced nanoparticle‐nanofibrous membrane materials offer a promising platform for interface applications, featuring enhanced spatiotemporal configurations and wide‐ranging applicability.
