Abstract

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 81 in a sample even at high, moderate or low concentration, which is greatly valuable for practical application. Furthermore, the detection of alfatoxin 81 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 81 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 81 in a sample using the the sensor produced in the present invention has sensitivity of aflatoxin 81 detection of 1 ng/L (part per trillion)
