Studies from Islamic Azad University Yield New Information about Peroxidases (Manufacturing a Modified Carbon Paste Electrode with Catalase Enzyme-Au Nanoparticles for Electrochemical Sensing of Hydrogen Peroxide and Their Electrocatalytic ...)
By a News Reporter-Staff News Editor at Biotech Week -- Fresh data on Enzymes and Coenzymes are presented in a new report. According to news reporting from Tehran, Iran, by NewsRx journalists, research stated, "To find hydrogen peroxide, different techniques applied, recently. In this practice we decided to produce a modified carbon paste electrode by catalase enzyme-Au nanoparticles for electrochemical sensing hydrogen peroxide and their electroactivity characteristics."
The news correspondents obtained a quote from the research from Islamic Azad University, "Cyclic voltammetry were done electrochemical researches. A three-electrode method including a modified carbon paste electrode with catalase enzyme-Au nanoparticles as the operant electrode, a platinum string electrode as a counter electrode, and saturated calomel electrode as a reference electrode, was applied. Cyclic voltammetric assays were done with different scan speed area from of 50 mV s(-1) to 500 mV s(-1). Transmission electron microscopy was checked external morphological characteristics of Au nanoparticles. H2O2 in 100 mu M to 450 mu M area could find out by designed biosensor."
According to the news reporters, the research concluded: "By perform assays in two weeks regular interval, the resistance of modified carbon paste electrode with catalase enzyme-Au nanoparticles biosensor has been determine and it has been discovered that after 14 days, modified carbon paste electrode with catalase enzyme-Au nanoparticles keeps its 97% activity."
