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 separation of propranolol enantiomers. The imprinted microparticles were in the size range of 0.2-0.5 micron as determined by scanning electron microscopy. The microparticles were suspended, in high concentration, in the electrolyte and used to perform enantiomer separation by a partial filling technique.
