Laser-Induced CuXO Formation on Copper for Enhanced Electrochemical Performance in Non-Enzymatic Glucose Sensing

Purdue researchers have developed a method for synthesizing Copper-Oxide (CuxO) structures directly onto copper surfaces. This environmentally friendly approach allows for the direct fabrication of electroactive CuxO structures without requiring additional reagents. The synthesized CuxO film can serve as a glucose sensor, maintaining around 90% of its initial sensitivity after fifty days. This innovative technique addresses the longstanding need for a direct, eco-friendly method of synthesizing CuxO structures on copper surfaces, while simultaneously enhancing their electrochemical sensing capabilities.
