英文摘要： In this study, fluorsecent metal nanoclusters (size<1.5nm) and metal nanoparticles(size<100nm) array with LSPR property are combined on the micro electrode array to make M-NCs/M-NPs A/SAM/MEA structure based light-addressable biochemical sensors with ultra-high spatial resolution. In this proposal, the sensing theoretical model will be studied first. Then the structure of sensors and fabrication processes will be given and optimized. Thirdly, the new light-addressable biochemical sensors with M-NCs/M-NPs A/SAM/MEA structure and coressponding light-addressable measurement system will be developed for further multi-channel biochemical detections. Finally, the characteristics of sensors will be tested and different biochemical detections will be achieved by our Light-addressable sensors. Compared to traditional silicon-based and QDs-based light-addressable biochemical sensors, the new light-addressable sensor designed by us here have many advantages,such as:ultra-high spatial resolution of sensor chips which will be lower than micrometers to hundreds of nanometers, higher spatial resolution of sensor system, higher sensitivity, faster response speed, lower limit of detection and more detectable biochemical molecules.What's more, it has better compatibility in fabrication and less toxicity in detection, which lead to better practicability. This study could provide new thoughts for multi-channel biochemical detection and nanomaterials based photoelectrochemical sensors.
