Organic Polymer and Metal Nano-particle Based Composites for Improvement of the Analytical Performance of Electrochemical Biosensors

Abstract

Metal nanoparticles (NPs) are described in the nanoscale and made from either pure metals or their compounds such as oxides. Metallic NPs have certain indistinct functional groups due to which these can bind with any type of ligand, antibody and drugs. Organic polymers, which conduct electricity, are called conducting polymers (intrinsically conducting polymers). They behave like semiconductors by exhibiting metallic conductivity. Process-ability is the major advantage of conducting polymers. Nanocomposite is a novel material having nano-fillers scattered in a matrix with morphology and interfacial characteristics of nano-composites including their individual property that influence their characteristics. Conducting polymers and NP composites can enhance the rate of electron transport between the current collector material (electrode) and the electrolyte; therefore they have been employed in the construction of improved electrochemical sensors such as amperometric, catalytic and potentiodynamic affinity sensors.

Preparation and evaluation of some nanocarbon (NC) based composites for optoelectronic applications

“…For the formation of the nanocomposites, a variety of preparation methods have been used, including the microemulsion, sol gel method, and chemical oxidative process 12 .…”

Advancement in the Production and Applications of Conductive Polymers (CPs)

“…Conductive polymers are organic polymers which conduct electricity. They possibly exhibit metallic conductivity and can as well be semiconductors [1,2]. Their major benefit is their processability, mostly via dispersion.…”
