| 摘要 |
The present invention relates to a biological sensor more particularly for detecting aflatoxin B1 in a sample and method of preparation thereof. The advantage of the present invention provides a rapid and efficient detection of aflatoxin B1 in a sample even at high, moderate or low concentration, which is greatly valuable for practical application. Furthermore, the detection of alfatoxin B1 of the present invention requires a simplified pretreatment of sample. Thus, the entire process of sample pre-treatment is simple and fast. Moreover, the detection of aflatoxin B1 by the sensor and the portable reader of the present invention are operated at a simple operation procedure. In another aspect of the present invention, the sensor has produced a high sensitivity. The lowest detectable limit of the aflatoxin B1 in a sample using the sensor produced in the present invention has sensitivity of aflatoxin B1 detection of 1ng/L (part per trillion) |
