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.
Claims14
A plurality of macroreticular polymer beads comprising a copolymer having a plurality of complexing cavities which selectively bind Au(S2O3)23−, wherein the copolymer is prepared from:
- (a) a cationic ligand monomer complexed to a non-metal surrogate ion selected from the group consisting of tetrathionate, hexathionate;
- hexadionate, heptyldionate, octyldionate;
- 1,4-phenylene diacetate;
- butane disulfonate, pentane disulfonate, and hexane disulfonate,
- (b) a non-ligand monomer, and
- (c) a crosslinking monomer;
- wherein the charge of the copolymer in the complexing cavity is opposite the charge of the target metal ion.
