Functionalization of La0.7Sr0.3MnO3 nanoparticles with polymer: Studies on enhanced hyperthermia and biocompatibility properties for biomedical applications

► The novelty of our work is that the LSMO nanoparticles are synthesized by simple and cost effective solution combustion synthesis. ► Particles are further coated with dextran and done all the fundamental characterizations. ► Dextran coated particles shows very low aggregation and better magnetic fluid hyperthermia properties. ► The reported low cytotoxicity of coated LSMO nanoparticles is an additional advantage for the application of these nanoparticles in the biomedical field.
