Here, a microchip-based electrochemical biosensor is developed that directly detects the quantal release of neurotransmitters from living rat pheochromocytoma (PC12) cells. Unlike traditional electrochemical sensors that mainly measure neurotransmitters in a homogeneous solution, our electrochemical micro-biosensors have an ultra-high sensitivity and can simultaneously measure spikes produced by t...Show More
A novel multi-dimensional 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. For the multi-dimensional multi-level sensing nanostructure construction, nanosheet of graphene oxide (GO) is herein served as nano-substrate. By using hydrothermal method, ZnO nanowires are ...Show More
