摘　　要：由藻类产生的海洋毒素对人类健康和环境安全构成了较大威胁,对其进行快速准确的检测是减小海洋毒素危害的有效手段之一。电化学生物传感器具有快速简便、灵敏度高、检测限低和成本低等特点,为检测海洋毒素提供了新的技术途径。目前,应用于海洋毒素检测中的电化学生物传感器主要有免疫传感器、酶传感器和DNA传感器等。本文综述了迄今为止国内外海洋毒素电化学生物传感器研究所取得的成果,并对其当前研究存在的问题和未来发展趋势进行探讨和展望。Marine toxins produced by harmful algae have a significant threat to human health and environmental safety. In order to reduce the risk of marine toxins,rapid and accurate detection of the toxins is one of the effective methods. Electrochemical biosensors provide a new technique for accurate marine toxins analysis due to their characteristics of time saving,simplicity,high sensitivity,low detection limit,and low cost. Nowadays,the electrochemical biosensors used in marine toxin detection mainly include immunosensors,enzyme sensors and DNA sensors. In this article,the achievements on marine toxin electrochemical biosensor made so far are reviewed. Meanwhile,the current problems and development trend of marine toxins biosensors are discussed and prospected.
