The goal of this Major Qualifying Project was to develop a stable and sensitive interface architecture for an easy and reusable non-enzymatic electrochemical glucose biosensor. This was achieved by changing the copper oxide nanoparticle morphology that was deposited onto a titanium oxide nanotube array. The interface architecture was manipulated by varying the concentration of the equimolar CuSO4/H2SO4 solution from 7.8 mM to 250 mM during electrodeposition. Through SEM imaging, cyclic voltammetry scans, and chronoamperometric readings, it was determined that the biosensor interface architecture affected its overall glucose sensing capabilities. The most ideal interface architecture was produced in an electrolyte solution of 50 mM CuSO4/H2SO4.
