Synthetic mycotoxin adsorbents and methods of making and utilizing the same
The present invention relates generally to molecularly imprinted polymers (MIPs). In particular, the present invention relates to reusable, ecologically friendly MIPs that can be produced in relatively large quantities, methods of producing the same, and methods of utilizing the same (e.g., to sequester and/or adsorb target compounds (e.g., mycotoxins)). Compositions and methods of the invention find use in a variety of applications including dietary therapeutic, prophylactic, food and beverage processing and manufacture, as well as research, quality control and traceability applications.
