Abstract:
Sensing with the aid of metal oxides and CNTs is the most vibrant field of
electrochemical science, which endows an ambit for various innovative and novel
functions with a variety of applications. Enzymatic sensors are costly, lack of stability,
have difficult immobilization techniques as well as electrodes used for electrochemical
analysis of neurotransmitter concentrations are also unable to monitor the potential of
these species. Besides, sensors with the most robust and reliable electrodes generally
tend to deteriorate over months of use. Therefore, a study has been designed to
synthesize CNTs based metal oxides nanoparticles by green synthesis method using the
lignin as a modifier and reducing agent. The synthesize materials have been
characterized by different techniques, i.e. SEM, XRD, and FTIR for surface
morphology, determination of nanostructure, and functionalization of surface. The
synthesized materials such as C2O3@CNTs/lignin, and CuO@CNTs/lignin have been
used for the surface modification of glassy carbon electrode (GCE). These composites
are supposed to be used as a promising material for dopamine sensing by giving
excellent electrochemical properties.
