Abstract

High sensitivity and accuracy are strongly required for biosensors due to their special application in the life and health of humans. In order to greatly enhance the above two parameters of the prepared biosensor, the architectures of Prussian blue and Au were purposefully designed. A single layer of PB grid with tight nano-holes was constructed to serve as a mould for the constraint of further Au deposition. Based on the steric hindrance effect, the Au crystal can be pushed towards one direction to in situ form a shape of a micro-cypress. Under a very low operation potential, −0.05 V, this composite film has been confirmed to own excellent abilities of performance enhancement and anti-interference as a glucose biosensor. This synthesis strategy can be expected to provide inspiration for morphology control of materials and high performance development of biosensors.
