To Analyses of Bioelectrodes Based on NS-Pani for the Estimation of Target Analytes

Abstract

By applying a DC electric field, charged powder particles that are suspended or distributed in a liquid media are drawn to and deposited onto a conductive substrate that has the opposite charge. This process is known as electrophoretic deposition, or EPD. The use of EPD derived from a colloidal suspension of a preferred conducting polymer (CP) offers a novel approach for customising nano-structured films with unique shape and packing density. It is well known that this novel and intriguing deposition method produces homogeneous, porous, pinhole-free CP films. Because of their small size, nano-structured conducting polymers, also known as nanotubes, nanorods, or nanospheres, have intriguing optical, electrical, and mechanical properties that present excellent opportunities for fusing biological recognition events with electronic signal transduction in the design of next-generation bioelectronic devices.  Because of its special qualities, including (i) increased surface area for effective protein/enzyme immobilization, (ii) unique electron transfer capabilities, (iii) shorter penetration depth for target molecules, (iv) broad range of tuneable properties, (v) biocompatibility, (vi) long-term environmental stability, etc., nano-structured polyaniline (NS-PANI) is predicted to be an effective platform for designing diverse biosensing systems.
