Caratterizzazione di Elettrodi in Diamante Borato

In this study diamond multi electrode arrays (MEAs) fabricated from planar boron-doped nanocrystalline diamond (BNCD) thin-?lms are depicted in their composition and performance. BNCD thin ?lms were characterized after the growth in the parameters of concentration of carriers and charge mobility by Hall e?ect measurements, and in the crystal quality of the surface by Raman spectroscopy and cyclic voltammetry. A further characterization of the electrode- electrolyte system was investigated to analyze the charge transfer during biological measurements, and an equivalent electrical circuit representing the electrochem- ical cell was derived. A particular attention focused on the noise of the entire setup involved during the biological experiments; after a detailed analysis of the non-negligible noise contribution coming from high-gain transimpedance ampli?ers and from the data acquisition u
