Single-wall carbon nanotubes (SWNTs) functionalized with carboxylic acid groups exhibit stable redox behavior and act as effective electrocatalysts for biomolecule oxidation on glassy carbon electrodes.

Area of Science:

Electrochemistry
Materials Science
Nanotechnology

Background:

Single-wall carbon nanotubes (SWNTs) are nanomaterials with unique electronic properties.
Functionalization of SWNTs can tailor their electrochemical behavior.
Glassy carbon electrodes are widely used in electrochemical studies.

Purpose of the Study:

To investigate the electrochemical behavior of carboxylic acid-functionalized SWNTs on a glassy carbon electrode.
To explore the electrocatalytic activity of the modified electrode towards biomolecule oxidation.

Main Methods:

Electrochemical studies on a glassy carbon electrode modified with SWNTs.
X-ray Photoelectron Spectroscopy (XPS) and Infrared (IR) spectroscopy for characterization.
Cyclic voltammetry to determine redox behavior and kinetics.
