Abstract
Anthracnose caused by Bacillus anthracis is an acute infectious disease that has the greatest impact on grazing livestock and wild ungulates, and poses a serious threat to human health. Therefore, it is of great research significance and application value to develop a fluorescent sensor that can detect the markers of Bacillus anthracis. Based on this, a three-dimensional Cd-based MOF (Cd-DNPA) was synthesized by solvothermal method. It is worth noting that it exhibits high selectivity and high sensitivity to 2,6-pyridine dicarboxylic acid (DPA), the calculated Ksv is 2.3686 × 103 M−1, the detection limit (LOD) is as low as 3.04 μM. In addition, the sensor can be detected in actual samples, and the recovery value is 98% −103%, indicating that it has the potential for practical application.
