We report on novel ferrogels derived from polysaccharides (sodium alginate and chitosan) with embedded iron oxide nanoparticles synthesized in situ and their combination with thermally responsive poly(N-isopropylacrylamide) for externally driven drug release using AC magnetic fields. Samples were characterized by Raman spectroscopy, transmission electron microscopy, and magnetic measurements. The obtained nanoparticles were found to be of ∼10 nm average size, showing magnetic properties very…
