针对现有农药检测方法操作复杂、仪器贵重、不利于现场快速检测等问题，将自行研制的便携式表面等离子体共振生物传感器应用于高毒性农药蝇毒磷的检测，采用直接法检测抗体。提出连续检测法，对质量浓度分别为500、200、100、50、0 mg/L 的蝇毒磷小分子样品进行了连续检测实验。通过实验证明了该装置和方法的可行性。基于表面等离子体共振的无标记蝇毒磷检测方法简单，仪器便携，操作简便，可实现现场快速检测。

The self-developed portable surface plasmon resonance biosensor is used in the detection of highly toxic pesticide coumaphos, as the existing pesticide detection methods are complicated, with precious instrument, and not conductive to on-site rapid detection. The antibody direct detection experiments are conducted; the continuous detection method is proposed and preceded in small coumaphos molecules with concentrations of 500, 200, 100, 50 and 0 mg/L. The validity of this method and the device is demonstrated by experiments. The unmarked coumaphos detection method based on the surface plasmon resonance is simple. The developed device is portable and easy to operate. The rapid and real-time detection can be realized by this method.
