Amperometric sensor for hydrogen peroxide based on electric wire composed of horseradish peroxidase and toluidine blue-multiwalled carbon nanotubes nanocomposite.
A kind of nanocomposites with good dispersion in water was prepared through noncovalent adsorption of toluidine blue (Tb) on multiwalled carbon nanotubes (MWCNT) for electric communication between horseradish peroxidase (HRP) and electrode. The nanocomposites could be conveniently cast on electrode surface. With the aid of chitosan, HRP was then immobilized on the nanostructure to form a reagen...
متن کاملA nanocomposite-based electrochemical sensor for non-enzymatic detection of hydrogen peroxide
Hydrogen peroxide (H2O2) plays important signaling roles in normal physiology and disease. However, analyzing the actions of H2O2 is often impeded by the difficulty in detecting this molecule. Herein, we report a novel nanocomposite-based electrochemical sensor for non-enzymatic detection of H2O2. Graphene oxide (GO) was selected as the dopant for the synthesis of polyaniline (PANI), leading to...

متن کاملAmperometric sensor for hydrogen peroxide based on immobilized cytochrome c on binary self-assembled monolayers.
A sensitive sensor for the determination of hydrogen peroxide (H(2)O(2)) was fabricated by immobilizing cytochrome c (cyt c) on binary self-assembled monolayers (SAMs) of 5-(1,2-dithiolan-3-yl)valeric acid (thioctic acid, T-COOH) and 5-(1,2-dithiolan-3-yl)valeramide (thioctic acid amide, T-NH(2)) on gold electrodes. The electrochemical characteristics of immobilized cyt c were investigated by c...
