Abstract

In this work, a combination of optical and electrochemical studies are performed in order to elaborate a suitable porous silicon (PSi) substrate for biosensing and biomaterial applications. We report on the electrochemical behavior of PSi multilayer stabilized by thermal oxidation, applying electrochemical impedance spectroscopy and cyclic voltammetry measurements. The strength of the method is evidenced when adsorption of small (12-mer) peptides is monitored. Our aim is to combine the advantages offered by the large sensing area of the PSi multilayers and the high sensitivity of the electrochemical technique for improved biosensing.
