Silver Nanoparticles Decorated Polyaniline Nanowires-Based Electrochemical DNA Sensor: Two-step Electrochemical Synthesis

In this work, silver nanoparticles decorated onto polyaniline nanowires were synthesized site-specifically onto Pt working electrodes (with only 0.8 mm2 area) using a novel, rapid, and effective electrochemical procedure: electropolymerization of PANi NWs and electrodeposition of AgNPs. The complementary properties of PANi NWs and AgNPs were obtained, including high surface area, high electrochemical activity, high biocompatibility, high...
