Migration behavior of the polymer particles possessing carboxylate and borate moieties in capillary electrophoresis

Migration behavior of functional polymer particles, such as carboxylic acid - and phenylboric acid-modified polymer particles, was examined in capillar y electrophoresis (CE) using migration buffers containing metal ions or sac charides. It was found that the interaction between functional groups on th e particles and the specific chemical species in the migration buffers infl uenced the migration behavior of the polymer particles. The obtained result s supported the possibility that CE becomes useful method for examining the property of functional polymer particles.
