Abstract

Auโ€Pt bimetallic nanoparticles film used as an efficient electrochemical sensor was prepared by selfโ€assembled Auโ€Pt bimetallic nanoparticles on a glassy carbon (GC) substrate using thioglycolic acid as a linker. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) showed that the Auโ€Pt nanoparticles selfโ€assembly film was dense and uniform. Electrochemical experiments revealed that Auโ€Pt bimetallic nanoparticles film/GC electrode showed high electrocatalytic activity to the oxidation of nitric oxide.

In this paper, self-assembled Prussian blue nanoparticles (PBNPs) on carbon ceramic electrode (CCE) were developed as a high sensitive hydrogen peroxide (H 2 O 2 ) electrochemical sensor. The PBNPs film was prepared by a simple dipping method. The morphology of the PBNPs-modified CCE was characteriz

## Abstract A glassy carbon electrode modified with carbon nanotube and bimetallic inorganicโ€organic nanofiber hybrid nanocomposite was prepared and used for determination of trace levels of guaifenesin. A modified glassy carbon electrode was developed for the rapid, selective, sensitive and low co
