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 -3M. The proposed sensor showed a high sensitivity of 69.12mV/decade with R=0.9934 for sensing of glucose. A fast-response time less than 4s with good selectivity, reproducibility and negligible response to common interferents such as ascorbic acid and uric acid prevailed. 2012-03-30T06:50:37Z 2012-03-30T06:50:37Z 2011-08 Article Micro and Nano Letters, vol. 6 (8), 2011, pages 609-613 1750-0443 http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6012997&tag=1 http://hdl.handle.net/123456789/18644 en The Institution of Engineering and Technology
