摘　　要：针对食品安全检测,构建了一种角度扫描型便携式表面等离子体共振生物传感器。详细介绍了光学系统、硬件电路及软件设计。并以盐酸克伦特罗(瘦肉精的一种)为检测样品,通过在传感器芯片固定生物探针,对浓度分别为2 mg/L、4 mg/L、8 mg/L、16 mg/L和32 mg/L的盐酸克伦特罗抗体进行了连续检测实验。实验结果符合生物分子免疫反应规律,证明了该装置的可行性。该装置便携、易操作,在食品安全检测领域具有广泛应用前景。A portable scanning surface plasmon resonance biosensor was constructed for the safety detection of food. The optical system, hardware circuit and software design were thoroughly introduced. The clenbuterol hydrochloride was used as samples, and the biological probe was fixed on the sensor chip. Clenbuterol hydrochloride antibody with different concentration as 2 mg/L, 4 mg/L, 8 mg/L,16 mg/L, and 32 mg/L were continuously detected. The experimental results accord with the immune response rule of biological molecules. The validity of this method and device was demonstrated by experiments. The device is portable and easy to operate. The device has extensive prospect in the safety detection of food.
