Deposition of silver nanoparticles with controllable density on the conducting polymer film

Deposition of Ag nanoparticle on the surface of polyaniline was discussed. Based on the electrostatic interaction, the Ag nanoparticles were deposited on the conducting polymer surface with controllable coverage by adjusting the deposition duration. Moreover, the selective deposition on the patterned polyaniline was performed. The noble metal nanoparticles are often employed in the biotechnology, and the combination of the nanoparticle and the conducting polymer may endow the conducting polymer more application in the biosensors.
