Synthesis of Highly Dispersed Ag Nanoparticles under Microwave Irradiation with PAMAM Dendrimer as Reductant and Stabilizer for Nonenzymatic Detecting Hydrogen Peroxide

Abstract:

A simple and sensitive electrochemical method for the nonenzymatic detection of hydrogen peroxide (H₂O₂) has been proposed. Highly dispersed Ag nanoparticles (NPs) were synthesized under microwave irradiation with PAMAM dendrimer as reductant and stabilizer. The formation of Ag NPs decorated with PAMAM dendrimer (Ag-G3.5-PAMAM) was confirmed by ultraviolet visible spectrophotometer (UV-vis). The as-prepared Ag-G3.5-PAMAM was used to modify the glassy carbon electrode (GCE) for nonenzymatic detection of hydrogen peroxide. It is showed that the fabricated electrochemical sensor based on Ag-G3.5-PAMAM exhibits fast response to hydrogen peroxide.The result indicates that Ag-G3.5-PAMAM may have promising applications in the development of nonenzymatic sensor for hydrogen peroxide in the future.
