Multifunctional biosensor based on ZnO nanostructures

摘要: The present invention provides the multifunctional biological and biochemical sensor technology based on ZnO nanostructures. nanotips serve as strong DNA or protein molecule binding sites to enhance immobilization. Patterned are used provide conductivity-based biosensors. also gate for field-effect transistor (FET) type sensors. integrated with SAW BAW These nanotip devices operate in multimodal operation combining electrical, acoustic optical sensing mechanisms. biosensors can be arrayed combined into one biochip, which will sensitivity accuracy of detection due immobilization capability. Such useful RNA-DNA, DNA-DNA, protein-protein, protein-DNA protein-small molecules interaction. It further applied drug discovery, environmental monitoring protection.
