The synthesis of MIPs involves the following steps: 1. Template Molecule: A template molecule, which is the target molecule, is chosen. 2. Polymerization: Functional monomers that can interact with the template molecule are polymerized in the presence of cross-linkers to form a solid matrix around the template. 3. Template Removal: The template molecule is removed, leaving behind cavities that match the template's shape, size, and functional groups.
