摘要：
Monodisperse polystyrene nanospheres with different diameters and functional groups were synthesized by soap-free emulsion polymerization. Capillary electrophoresis (CE) was applied to the separation and detection of the nanospheres. Baseline separation was achieved for carboxylic and sulfonic functionalized colloids due to their difference in diameter and surface charge. The electrophoretic mobility of the sulfonic functionalized colloids decreased with increasing of particle size, and three sulfonic functionalized nanosphere samples with diameters of 190, 250 and 330 nm were separated successfully by CE.
