Growth of nanostructured CuAl alloy films by magnetron sputtering for non-enzymatic glucose-sensing applications.

Enzymatic glucose sensors usually exhibit excellent sensitivity and selectivity but suffer from poor stability due to the negative influence of temperature and humidity on enzyme molecules. As compared to enzymatic glucose sensors, non-enzymatic counterparts are generally more stable but are facing challenges in concurrently improving both sensitivity and selectivity of a trace amount of glucose molecules in physiological samples such as saliva and sweat. Here, a novel non-enzymatic glucose sensor based on nanostructured CuAl alloy films has been fabricated by a facile magnetron-sputtering followed by controllable electrochemical etching approach.
