Research of multi-parameter measuring system based on MEMS electrodes modified nanoparticles

Based on MEMS technology, electrodes surface modified technology, technique of immobilized enzyme and electrochemical detecting principle, the biosensors for detecting different biochemical parameters was fabricated based on MEMS electrodes modified nanoparticles. The multi-parameter measuring system is designed by using potentiostat for amperometric chemical sensors. The characters of the microsystem has been demonstrated with the detection of glucose parameter, compared with the data obtained from the instrument CHI660A showed that it has a good linear relation in the linear range of 0.5-22 mmol/L, and the correlation coefficient was 0.9943.
