Iranian researchers managed to make an economical easy-to-use nanosensor which could be used for measuring hydrogen peroxide precisely in medical and food industries.
"Our research group managed to produce electrocatalysts as nanofilms and nanoparticles by simple methods and cheap raw materials so that they show high stability and good catalytic properties," Habib Razmi said to the news service of INIC.
"This means that we can use them in the production of electrochemical sensors to be utilized in different industries."
"We synthesized organic polymeric electrocatalysts from organic precursors like anylene, orthophenylene diamine, and pyrol by means of electropolymerization at optimized conditions. In a similar way, we made mineral electrocatalysts by some of the intermediate metallic salts and hexacyano metalates through chemical derivation, electrochemistry or electropolymerization at optimized conditions. These thin polymeric layers were synthesized on electrode beds such as palatine or carbon ceramics", he added.
Razmi described low costs, simplicity of fabrication, chemical and mechanical stability of the modified electrode used as amperometric sensor for hydrogen peroxide measurement as advantages of this research and product.
The accurate and precise measurement of hydrogen peroxide is of great importance in medical and food industries. The proposed sensor could be an appropriate alternative for classic methods due to its economy and simplicity.
