ZnO nanorods and tripods have been deposited on Si substrates by vapor–solid technique. Field-emission scanning electron microscopy reveals the formation of distinct morphologies at different growth conditions. ZnO nanostructures having high isoelectric point (9.5) have been used for the adsorption of low isoelectric point enzymes for the detection of glucose. The increment of current in fabricated amperometric biosensor with the addition of glucose is attributed to good catalytic behavior of GO x /ZnO nanostructures. The sensor achieves 90% of steady state current in less than 10 s indicating a fast electron exchange between GO x and ZnO nanostructures. A quantitative comparison of the responsivity of biosensor for ZnO nanorods and tripods is presented. The sensitivity of ZnO tripods biosensor is found to be 30% higher than that of ZnO nanorods.
