OBJECTIVES: Due to systematic side effects, there is a growing interest in nanoparticle formulation of anticancer drugs. Here, we aimed to synthesize poly (styrene-alt-maleic anhydride) cross-linked by melamine (PSMA/Me) and coated with magnetite nanoparticles (MNPs) PSMA/Me/Fe METHODS: Novel PSMA/Me was synthesized via free radical copolymerization, coated with Fe RESULTS: Characterization methods confirmed PSMA/Me copolymer formation. The results showed a significant encapsulation efficiency of 83%. The drug release analysis exhibited that PSMA/Me/Fe CONCLUSIONS: Our results indicated that PSMA/Me/Fe
