Molecularly imprinted polymers(MIPs),as one of the most attractive research topics,offer unique advantages,such as high selectivity,predefined recognition properties,ease of preparation,low-cost production. The recent developments in the field of MIPs-based chemical sensors and sensor arrays are reviewed. The individual sensors with high selectivity,including electrochemical sensors,photochemical sensors and quality sensitive sensors are presented. Sensor arrays based on cross-reactivity of MIPs show limited application. Specifically,photochemical sensor arrays are discussed. The future development of MIPs-based sensors and sensor arrays would be guided by the understanding of imprinting process. MIPs-based sensors and sensor arrays chould show potential application in various fields,such as food analysis,drug control and environmental monitoring.
