local.description.resumoStainless Steels (SS) are promising candidates to constitute the transducer substrate of devices for electrochemical sensing mainly due to their high electrical conductivity, biocompatibility and relative low cost. In this study, the corrosion resistance of SS was examined in four solutions that represent the environment of biosensors in real applications: 0.01 M Tris buffer (pH 7.4), an electrolyte containing Tris and 0.1M KCl as supporting source of ions, Hanks’ solution to simulate body fluids and, also, a solution to represent the electrolyte commonly used to performed Cyclic Voltammetry (CV). Potentiodinamic anodic polarization, Chronoamperometry and images of Optical Microscopy revealed that the Hanks’ and CV solutions were the most aggressive media to the SS electrodes, which remained chemically stable in both Tris and electrolyte during 16h under the influence of critical potentials. When functionalized to recognize venom from Crotalus snakes, the SS suffered an increase of the diameter of the capacitive arc in the EIS experiment as a result of the detection of the target analyte, corroborating it is a promising electrochemical transducer for application in biosensors.
