Abstract
A composite electrode includes a polypyrrole matrix, and metal nanoparticles coupled to the polypyrrole matrix. Assessing the presence of an analyte includes placing the composite electrode in a solution to be tested for the analyte, applying an electrical current to the electrode, and assessing the presence of an oxidation peak at a predetermined voltage with respect to a reference electrode. The presence of the oxidation peak at the predetermined voltage indicates the presence of the analyte. Fabricating the composite electrode includes electropolymerizing a polypyrrole matrix onto a metal substrate, separating the polypyrrole matrix from the metal substrate, and electrodepositing the metal nanoparticles onto the polypyrrole matrix to yield the electrode.
