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.

Technology Validation:

- Cyclic Voltammetry was used to detect presence of high levels of electrochemically active species on the surface of LIO samples


- Environmentally friendly synthesis method without the need for additional reagents

- Direct synthesis of CuxO structures onto copper surfaces

- CuxO structures with enhanced catalytic activity and stability

- Adjustable power output of the laser for controlled synthesis CuxO film can be used in sensor applications


- Sensors, e.g. glucose sensor

- Improve patient care and response to glucose levels
