Article Preview

In this work two different synthesis processes for Single-Wall Carbon Nanotubes deposition (such as the Hot Filament-Chemical Vapor Deposition, HF-CVD, and the electrophoretic deposition, EPD) on microwire surfaces, were described. Then, the morphological and structural characterization of SWNT-modified microwires were performed by Scanning Electron Microscopy (FE-SEM) and Raman Spectroscopy, respectively. Finally, the nanostrcutured microelectrodes were electrochemically characterized using NADH, NAD+, epinephrine, and ascorbic acid (AA), useful biological molecules to develop electrochemical sensors and biosensors.
