分子印迹在化学传感器及阵列领域的研究进展

摘要

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.%分子印迹聚合物因其具有高选择性、预定识别性、制备简单、价格低廉等优点，成为当前研究的热点之一。本文对分子印迹聚合物在化学传感器及传感器阵列领域的应用进展进行了综述。作为选择性化学传感器，重点探讨了分子印迹聚合物在电化学传感器、光化学传感器和质量敏感型传感器中的应用。相对于分子印迹传感器，基于分子印迹聚合物交叉敏感性原理的分子印迹聚合物传感器阵列的应用较少，仅对有限例子的光化学传感器阵列进行了探讨。受益于印迹机理的深入理解，分子印迹化学传感器及其阵列将在食品分析、药物控制、环境监测等领域表现出较好的应用前景。
