Magnetic chitosan microgels: Synthesis, characterization, and evaluation of magnetic field effect over the drug release behavior

Magnetic microgels based on chitosan, modified with glycidyl methacrylate (GMA) and activated with folic acid (FA), and cobalt ferrite nanoparticles, modified with GMA (GMACoFe2O4), were synthesized by emulsion polymerization. The size of the round-shaped microgels, with and without GMACoFe2O4, ranged from (1.62 ± 0.38) μm to (1.71 ± 0.61) μm, respectively. Their release behavior was evaluated in the presence and absence of a magnetic field...
