Adv Healthc Mater. 2017 Mar;6(6):10.1002/adhm.201601080. doi: 10.1002/adhm.201601080. Epub 2017 Jan 25.

Abstract

A dual-layer shell hollow nanostructure as drug carrier that provides instant on/off function for drug release and contrast enhancement for multimodal imaging is reported. The on-demand drug release is triggered by irradiation of an external magnetic field. The nanocarrier also demonstrates a high drug loading capacity and synergistic magnetic-thermal and chemotherapy.

Keywords: chitosan valve; drug carriers; multimodal imaging; on/off release; synergistic therapy.
