Biosensor

摘要

The biosensor is the biological element that is assembled on the sensor system. The whole system combines the biomedical and engineering technologies. This report describes the biosensor technologies which include the principle, type, interface and measuring systems. Some types will be presented, including the electrochemical, piezoelectric and optical biosensors. The biosensor will be designed for the purpose that the detection is fast, stable, high specificity, high selectivity, high sensitivity and user friendliness, which can be widely applied in the medical development, immunoassay, drug screening, agriculture industry and environment monitoring.
