Title: Studies on Ion Conducting Membranes for Electrochemical Applications
Authors: PRAKASH S.
Keywords: polymer
Issue Date: 30-May-2012
Abstract: In the course of the current study we found that the stabilized new nanocomposites can be formulated for enzyme free glucose sensor using a poly (dimethylaniline), SPEEK and copper nanoparticles. The SPEEK/PDMA/CuNFs/GCE fabricated sensor electrochemically boasts a number of advantages such as high sensitivity, good stability,reproducibility, and quick response. Excellent selectivity was rendered by the nanocomposites film and signals from oxidation of common interfering species such as UA and AA can be effectively suppressed. The remarkable performance was attributed to synergistic electrocatalytic activity combining a CuNFs and PDMA in the presence of SPEEK, and the large electro-active surface area of CuNFs. Also, the developed sensor is a potential candidate for routine glucose analysis in real blood serum samples. This methodology would be extended for the development of other biosensors.
