Membrane-free, rhodium-modified, methyl silicate-graphite amperometric biosensor

A rhodium-modified amperometric biosensor based on the recently introduced ceramic-carbon composite electrode has been developed. The sensors are comprised of Rh metal and glucose-oxidase-modified graphite particles embedded in a porous, organically modified silicate network. The hydrophobicity of the matrix imparts limited wettability. The thickness of the active layer of the electrode can be tuned by incorporating hydrophilic components such...
