| Abstract: | The excellent detection sensitivity in various matrices of T‐2 toxin (T‐2), which has cytotoxic and immunosuppressive effects in DNA and RNA synthesis, is a highly desirable characteristic. A sensitive molecularly imprinted electrochemical sensor was constructed for the selective detection of T‐2. In this study, iron ions (Fe3+) were introduced to increase the chelation of the metal ions and templates for preparing molecularly imprinted polymers (MIPs). With the increased chelation of the metal ions and templates, the selectivity and sensitivity of the MIPs were effectively improved. The imprinted sensor was successfully employed to detect T‐2 in cereals and human serum samples. |
