Findings in Urea Reported from Razi University

June 3, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Urea is now available. According to news reporting from Kermanshah, Iran, by NewsRx journalists, research stated, "This work describes the electrochemical behavior of Ni-2,3-pyrazine dicarboxylic acid (Ni-PDA) film immobilized on the surface of penicillamine (PNA)/CdS-quantum dots (CdS-QDs) gold nanoparticle (AuNPs) Au electrode and its electrocatalytic activity toward oxidation of urea. The surface structure and composition of the sensor was characterized by scanning electron microscopy (SEM)."

The news correspondents obtained a quote from the research from Razi University, "Oxidation of urea on the surface of modified electrode was investigated with cyclic voltammetry, electrochemical impedance spectroscopy (EIS), hydrodynamic voltammetry and chronoamperometry methods and the results showed that the PNA/CdS-QDs/PDA-Ni film displays excellent electrochemical catalytic activities towards urea oxidation. The modified electrode indicated reproducible behavior and high level of stability during the electrochemical experiments. Also it has short response time, low detection limit, high sensitivity and low operation potential. It can be used as an amperometric sensor for monitoring of urea."

According to the news reporters, the research concluded: "The proposed modified electrode was successfully used for determination of urea in real sample such human serum."
