Carbon electrode used as working electrode in general. But carbon electrode has low sensitivity, biocompatability, and low signal. Herein we demonstrate a straightforward signal amplification technique by employing nanostructured electrode surfaces. Three different types of nanostructured metal surfaces (i.e., platinum black, gold black, and mesoporous platinum) will be investigated in terms of degree of signal amplification, stability, and reproducibility. In addition, a series of metal electrodes with different surface areas and nanostructures will be prepared by varying metal deposition conditions (e.g., metal salt concentration, deposition time/temperature, and type/concentration of surfactants). Platinum black is one of electro deposition method using cyclic voltametry. And the mesoporous pt electrode was fabricated by using an electrodeposition technique with nonionic surfactant and hydrogen hexachloroplatinate hydrate (HCPA). Gold-black was deposited by reduction of gold chloride hydrate in solution. Finally we apply such nanostructured electrodes to electrochemical immunoassay of a cardiac biomarker, B-type natriuretic peptide (BNP).
