Molecularly imprinted microparticles for capillary electrochromatographic enantiomer separation of propranolol

Molecularly imprinted microparticles imprinted against (S)-propranolol were synthesised and studied for use in capillary electrochromatographic separa tion of propranolol enantiomers. The imprinted microparticles were in the s ize range of 0.2-0.5 mum as determined by scanning electron microscopy. The microparticles were suspended, in high concentration, in the electrolyte a nd used to perform enantiomer separation by a partial filling technique.
