Abstract: The preparation of single hole hollow microsphere of poly(AA-EGDMA) through the direct polymerization and cross linking reactions occurring at the surface of carboxyl capping polystyrene colloids was reported. The carboxyl-capping PS beads with a uniform size of 400 nm were synthesized using an emulsifier-free copolymerization. Acrylamide (AA) and ethylene glycol dimethacrylate (EGDMA) were used as the functional monomer and crosslinking agent for the shell materials. The results indicated that core-shell microspheres without holes are obtained if a one-step polymerization at 60C was used. The approach allows imprinting of various organic biological molecular at the single-hole hollow polymer microspheres towards the molecular recognition and high capacity uptake of target species
