The prepared (ZnO-NT) arrays were further used as electrochemical enzyme-based glucose sensors through immobilisation of glucose oxidase by the physical adsorption method in conjunction with a Nafion coating. The electrochemical response of the sensor was found to be linear over a relatively wide logarithmic concentration range from 0.5×10−6 to 12×10−3 M. The proposed sensor showed a high sensitivity of 69.12 mV/decade with R=0.9934 for sensing of glucose. A fast-response time less than 4 s with good selectivity, reproducibility and negligible response to common interferents such as ascorbic acid and uric acid prevailed.}, title = {Functionalised zinc oxide nanotube arrays as electrochemical sensors for the selective determination of glucose}, journal = {Micro & Nano Letters}, issue = {8}, volume = {6}, year = {2011}, month = {August}, pages = {609-613(4)}, publisher ={Institution of Engineering and Technology}, copyright = {© The Institution of Engineering and Technology}, url = {https://digital-library.theiet.org/;jsessionid=4fw9i7wchf69n.x-iet-live-01content/journals/10.1049/mnl.2011.0310} }
