文摘

We reported a synthesis of manganese dioxide-silver hybrid nanowire. The fast development of detecting small molecules inspired us to study the electrochemical properties of the nanocomposite. The hybrid nanowire was fabricated as a novel nonenzymatic hydrogen peroxide sensor with rapid, stable, and reliable response with a detection limit of 0.24 渭M. The enhanced electrochemical signal characteristic of silver can be easily distinguished which can be assigned to the small amount decoration of silver nanoparticles on the nanowire.
