Abstract
The present disclosure provides Molecularly Imprinted Polymer (MIP) technology for selectively sequestering one or more target molecules from chemical mixtures. Also disclosed herein are MIP beads and methods of making and using thereof.
Claims30
A plurality of macroreticular polymer beads comprising a copolymer having a plurality of complexing cavities which selectively bind a target metal ion, wherein the copolymer is prepared from:
- (a) a ligand monomer which is cationic or anionic and is complexed to a non-metal surrogate ion,
- (b) a non-ligand monomer, and
- (c) a crosslinking monomer;
- wherein:
- (i) the charge of the copolymer in the complexing cavity is opposite the charge of the target metal ion, and
- (ii) the non-metal surrogate ion has substantially the same shape and charge as the target metal ion.

A method of preparing macroreticular molecularly imprinted polymer beads comprising polymerizing:
- (a) a ligand monomer which is cationic or anionic and is complexed to a non-metal surrogate ion,
- (b) an uncharged monomer, and
- (c) a crosslinking monomer;
- thereby forming a plurality of macroreticular molecularly imprinted polymer beads, each having a plurality of complexing cavities which selectively bind a target metal ion, wherein the size and charge of the non-metal surrogate ion is substantially the same as the target metal ion.
