【Abstract】 In recent years, rapid development has been made in the research of ISFET (Ion-Sensitive Field Effect Transistor) as biosensors. Advantages of ISFETs over traditional ISE (ion sensitive electrode) are discussed. The operational mechanism of ISFETs is described. The classification of the device and its sensitive layer are summarized. Application and research of ISFETs for biomedicine in recent years are reviewed in particular. Moreover, the research and development trend of ISFET in the future are dealt with.更多还原
