Abstract

Multifunctional nanocomposite hydrogel: swelling-shrink transition of the magnetic sensitive poly(N-isopropylacrylamide)/Fe3O4 (PNIPAM/Fe3O4) nanocomposite hydrogel can be controlled via near-infrared (NIR) laser exposure or non-exposure, which shows potential as a movable position heating source manipulated by combination of an external magnet and near-infrared laser irradiation.

Keywords: Fe3O4 nanoparticles; N-isopropylacrylamide; NIR laser; magnetic hydrogel; photothermal.
