Zinc oxide biosensor for glucose detection.(SENSORS)
Advanced Ceramics Report, September, 2006
Researchers at Nanyang Technological University in Singapore have developed zinc oxide (ZnO) nanostructures that are suitable for electrochemical biosensors. In their work, the enzyme used for glucose detection, glucose oxidase, was attached to ZnO nanocombs, which resulted in a biosensor that exhibits a high affinity and sensitivity, and fast response for glucose detection.
This method of fabricating ZnO-based biosensors is simple and to be applicable to other enzymes and bioactive molecules on various metal oxide nanostructures.
One of the researchers, Professor Xiaowei Sun from the university's School of Electrical and Electronic Engineering, commented "Typical electrochemical glucose biosensors using gold electrodes have low sensitivity. Using our...
