摘要
微囊藻毒素检测生物传感器结合分子生物学技术和传感技术,将微囊藻毒素浓度信号转变为易于检测读取的电化学、光学等信号,具有操作简单、快速等优点。该文主要从电极修饰特点、检出限、检测时间、便捷性、实际应用等方面论述了当前国内外多种生物传感器在微囊藻毒素检测领域的研究进展;其发展趋势是与流动注射等技术相结合,灵敏度不断提高、检测步骤不断简化,操作更加方便,耗时更短,逐步实现多通道自动化、在线实时监测。
        Biosensors for detecting microcystins are user-friendly devices, which combine biological components such as antibody, antigen, enzyme with physicochemical detectors and can transform the signal of microcystins' concentration into easily quantified signal such as optical, electrical signal. The biosensors' electrode modification, detection limit, detection time and application for real sample determination were described in this review. The biosensors are becoming more sensitive, simplified, faster, more convenient to use and even automated for real-time on-line detection due to flow injection technology.
