摘要
Nobel metal nanoparticles are receiving increasing attention in many fields such as material chemistry, environmental science and pharmaceutical science. In this study, a facial synthesis of a gold nanoparticles (Au NPs) was carried out from Scutellaria barbata extract. The synthesized Au NPs was characterized by using UV-vis spectroscopy and X-ray photoelectron spectroscopy. The preparation process was highly rapid since the formation of Au nanoparticles was totally complete within 3 h. We further investigated the electrochemical properties of the biosynthesized Au NPs. A nonenzymatic H2O2 electrochemical sensor was shown to be successfully fabricated by using biosynthesized Au NPs. Moreover, the fabricated electrochemical sensor also showed good selectivity.
