A procedure for direct electrochemical deposition of poly(pyrrole-indole) on gold nanoparticles coated stainless steel wire was established, and the formation of copolymer was confirmed by infrared spectroscopy. The synthesized coating showed unique microstructure, excellent extraction efficiency (2–10 times of corresponding single-component coating), high thermal stability (up to 280°C) and good...
In this work, we report on the electrochemical behavior of bioconjugates prepared with gold nanoparticles (AuNP) capped with three different molecular layers (citrate anions, 6-mercaptopurine and ω-mercaptoundecanoic acid) and the protein hemoglobin (Hb). Freshly formed bioconjugates are deposited on a glassy carbon electrode and assayed for electroactivity. A pair of redox peaks with formal potential...
