[JPS-Cover Story] Magnetic Molecularly Imprinted Polymers Synthesized via Surface-Initiated Reversible Addition-Fragmentation Chain Transfer Polymerization for Enrichment and Determination of Synthetic Estrogens in Aqueous Solution
Magnetic molecularly
imprinted polymers have attracted significant interest caused by their multifunctionality
of selective recognition of target molecules and rapid magnetic response. In
this contribution, the magnetic molecularly imprinted polymers
were synthesized via surface-initiated reversible addition addition-fragmentation
chain transfer polymerization using diethylstilbestrol as the tem...
