A novel approach for preparation of thermoresponsive polymer magnetic microspheres with core-shell structure

Dual-responsive polymer microspheres with well-defined core-shell structure (see Figure) have been prepared via a template polymerization process. The resulting microspheres consist of a silica-coated magnetite core and a cross-linked poly(N-isopropylacrylamide) shell, which enable them to exhibit both magnetic response and thermoresponse.
