“…The carbon-based materials, such as graphene sheets [111], graphene oxide (GO) [112], reduced graphene oxide (rGO) [113,114], and carbon nano-based materials [115][116][117][118], are frequently used. Electrically conductive polymers, such as polyaniline (PANI) [119,120] and polypyrrole (PPy) [121] are also promising candidates for the supporting materials due to their low cost, large surface area, and manipulatable properties by functionalization treatments [122]. On the other hand, inorganic materials, such as TiO2 nanotube array [123] and the CoOOH nanosheets [124], are also widely utilized.…”

A comprehensive review of the electroactive materials for non-enzymatic glucose sensing and sensing devices has been performed in this work. A general introduction for glucose sensing, a facile electrochemical technique for glucose detection, and explanations of fundamental mechanisms for the electro-oxidation of glucose via the electrochemical technique are conducted. The glucose sensing materials are classified into five major systems: (1) mono-metallic materials, (2) bi-metallic materials, (3) metallic-oxide compounds, (4) metallic-hydroxide materials, and (5) metal-metal derivatives. The performances of various systems within this decade have been compared and explained in terms of sensitivity, linear regime, the limit of detection (LOD), and detection potentials. Some promising materials and practicable methodologies for the further developments of glucose sensors have been proposed. Firstly, the atomic deposition of alloys is expected to enhance the selectivity, which is considered to be lacking in non-enzymatic glucose sensing. Secondly, by using the modification of the hydrophilicity of the metallic-oxides, a promoted current response from the electro-oxidation of glucose is expected. Lastly, by taking the advantage of the redistribution phenomenon of the oxide particles, the usage of the noble metals is foreseen to be reduced.

“…Non-specific adsorption of proteins and biomolecules is always problematic when more hydrophobic materials are present on the electrode. PANI/MWCNTs ZnO LOD: 0.1 mM, two linear regions: 0.1 to 1 mM and 1 to 6 mM (10 mM NaOH) [168] PANI NiO LOD: 0.06 µM, linearity: 1-3000 µM [169] AuNPs = gold nanoparticles, AgNPs = silver nanoparticles, PANI = polyaniline, PPY = polypyrrole, MWCNT = multiwalled carbon nanotubes.…”

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.

“…The PANI as other CP is reversibly oxidized from its leucoemeraldine form to emeraldine involving 2 electrons in the process. Because of the advantage of the inherent proprieties cited above, PANI has been used in biosensors as well as a mediator [47][48][49][50][51][52][53][54] or as an immobilization matrix [55] for the detection of a wide range of analytes such as ammonia [56,57], glucose [58,59], cholesterol [60][61][62].…”
