Abstract

Novel thermal- and pH-responsive hollow nanocapsules (HNCaps) were fabricated through the grafting of a thiol-end capped PNIPAAm-b-PAA by thiol-ene “click” reaction onto PMMA HNCaps. The lowest critical solution temperature (LCST) of the fabricated HNCaps was obtained as 38–40°C. The fabricated nanosystem was loaded with doxorubicin hydrochloride (Dox), and its drug loading and encapsulation efficiencies were obtained as 62 and 53%, respectively. The in vitro stimuli-responsive drug release behavior of the fabricated nanomedicine was investigated extensively. The anticancer activity of the drug-loaded HNCaps was evaluated using MTT assay against MCF7 cells. The results exhibited excellent potential of nanosystem as a drug delivery system (DDS) for cancer chemotherapy. © 2020 Taylor & Francis.
