A facile method for grafting of bisphenol A imprinted polymer shells onto poly(divinylbenzene) microspheres through precipitation polymerization

► We directly graft bisphenol A imprinted polymer onto poly(divinylbenzene). ► Core-shell structures depend on the concentration of cores and precursor. ► These particles show clear selectivity to bisphenol A in solid-phase extraction. ► Leak of bisphenol A from these particles is not found after extraction.
