Implantable biosensors are an underdeveloped area of research which could provide many benefits to tumor detection. Utilizing an electrode that is selective toward the byproduct (H2O2) of many oxidase reactions enables a biosensor to be created through coupling of an enzyme layer. A biocompatible electrode with reactivity towards H2O2 is developed using Pt nanoparticles deposited on a titanium dioxide nanotube array. Titanium dioxide nanotubes were formed using anodic oxidation at varying potentials in an ethylene glycol based solution. Pt was deposited onto nanotube arrays of varying condition using cyclic voltammetry. Two electrodes with slight carbon deposits on the nanotubes showed reactivity with H2O2 at a potential around –0.277V.
