Molecularly imprinted membrane applied for selective separation

Molecular Imprinting Polymer (VHP) technique is well known for creating polymer materials with molecule selectivity in adsorption and separation. MIPs have mostly been prepared by bulk polymerization and grinding the resulting brittle polymer to prepare particles of the desired dimensions. However,...
