Low Cost Inkjet Fabrication of Glucose Electrochemical Sensors Based on Copper Oxide
The availability of low cost, efficient and wearable glucose sensors is one of the prerequisites for the development of ubiquitous sensors networks for the efficient monitoring of diabetes epidemiology. Starting from this principle, wet metallization and low cost inkjet printing were employed in the present work to manufacture non-enzymatic electrochemical sensors. CuO nanoparticles were inkjet printed on platinum, which was electrodeposited on stainless steel. The active layer obtained in this way showed an acceptable linear range for glucose detection and a good sensitivity when used as sensor. The influence on performances of interfering species and curvature were investigated, demonstrating a negligible effect for the first and a decrease in linearity of the response and sensitivity for the latter.
