Special Issue Information

Dear Colleagues,

Natural or synthetic polymers have played an important role in the development of chemosensors and biosensors due to their commercial availability at a low cost or ease of synthesis.  Conducting polymers, e.g., pyrrole and polyaniline,  serve as biocompatible matrices for the immobilization of biorecognition elements and impart detection selectivity and sensitivity. Nonconductive polymers, including chitin, chitosan, cellulose, dextran, and polystyrene, have also attracted considerable interest in their function as support matrices for enzymes, antibodies, DNA, etc. Bioconjugation of the amino-receptor with carboxylated dextran is a popular example. Carbon nanotubes, graphene, carbon dots, quantum dots, and metal nanoparticles form nanocomposites with conducting or nonconducting polymers to endow high electrical conductivity, effective surface area, and fast electron transfer rate. The combination of graphene and carbon nanotubes, in the form of 3D structures in polymers, represents a very interesting strategy to fabricate efficient, sensitive, and selective devices. Novel sensors can be constructed using sol-gel, ionic liquids, molecularly imprinted polymers, etc., within polymer nanocomposite matrices.

This Special Issue calls for papers that highlight the salient features of polymers together with nanomaterials to enhance speed, sensitivity, selectivity, and versatility of sensing/biosensing platforms. Nanocomposites prepared from polymers with carbon nanomaterials and metallic nanoparticles are opening up an emerging research area due to their excellent analytical performance.

Conducting polymers (CPs) have been at the center of research owing to their metal-like electrochemical properties and polymer-like dispersion nature. CPs and their composites serve as ideal functional materials for diversified biomedical applications like drug delivery, tissue engineering, and diagnostics. There have also been numerous biosensing platforms based on polyaniline (PANI), polypyrrole (PPY), polythiophene (PTP), and their composites. Based on their unique properties and extensive use in biosensing matrices, updated information on novel CPs and their role is appealing. This review focuses on the properties and performance of biosensing matrices based on CPs reported in the last three years. The salient features of CPs like PANI, PPY, PTP, and their composites with nanoparticles, carbon materials, etc. are outlined along with respective examples. A description of mediator conjugated biosensor designs and enzymeless CPs based glucose sensing has also been included. The future research trends with required improvements to improve the analytical performance of CP-biosensing devices have also been addressed. Full article
