Integrated Micro/Nano Structures as Electrodes in Biosensors

This paper presents a new process to develop integrated micro/nano 3D structures as well as usage of these structures as electrodes in biosensors. It also discusses the effect of anchoring molecules on the functionalization of the electrodes and their sensing performance in glucose detection. Results show that using electrodes with 3D structures improves the sensitivity of glucose sensors and that entrapping enzyme near the electrode surface within a porous polymer layer provides an efficient means for electron transfer.
