Multi-Dimensional and Multi-Functional Hierarchical Nanostructure for High Performance Sensing to Trace-Level Dopamine Molecules

Abstract

A novel iierarchical nanostructure constructed with three types of nano-building-block is used as electrochemical sensing material to detect trace dopamine which plays as neurotransmitter in body-fluids. The three building-blocks with different functions combined together exhibit synergistic effect during the detection to dopamine. The detection limit of the sensor to dopamine reaches sub-nM level.
