Electrochemical sensors using conducting polymer/noble metal nanoparticle nanocomposites for the detection of various analytes: a review

Noble Metal Nanomaterial-Based Biosensors for Electrochemical and Optical Detection of Viruses Causing Respiratory Illnesses

“…In this context, the use of noble metal nanoparticles has received increasing attention in electrochemical biosensors for several reasons. The incorporation of noble metal nanoparticles in the biosensing platform can enhance the electrical response signal because of its attractive properties, such as high electrical conductivity, high surface area, and effectiveness in adhering to biomolecules (Jo et al, 2019;John et al, 2021).…”

A facile and economic electrochemical sensor for methylmalonic acid: a potential biomarker for vitamin B12 deficiency

“…Also, their ability in improving operational efficiency, enhancement in electrical conductivity, and equivalent involvement in offering an ample amount of electron transfer kinetics for the electrocatalytic reactions ameliorate their utilisation. 20 Polyaniline (PANI), polythiophene (PTh), polyparaphenylene (PPh), polyacetylene (PA), polypyrrole (PPy), and poly(3,4-ethylenedioxythiophene) (PEDOT) are various types of conducting polymers that are extensively used as supporting catalyst materials and electrode modifiers. 21 PEDOT is found to be an interesting conducting polymer and therefore was utilised for electrochemically modifying the bare PGE due to its defect-free network forming ability as a polymer.…”

Recent advances in the aqueous applications of PEDOT

“…Conducting polymers (CPs) are one class of materials that have shown good compatibility with living organisms, good environmental stability, and excellent electrical function. [10][11][12][13][14] Among all CPs, poly(3,4-ethylene dioxythiophene) (PEDOT) stands out as the prototypical CP displaying a range of desirable properties (relatively high electrical conductivity, high ambient stability, biocompatibility, tunable optical properties, etc.). [15][16][17] The polymeric structure of PEDOT allows for electrostatic interaction with ions in the surrounding environment, making PEDOT an appropriate active material for sensor developments and controlled release drug delivery systems.…”
