On-command controlled drug release by diels-Alder reaction using Bi-magnetic core/shell nano-carriers.


PMID 27865903

Abstract

A novel bi-functional thermo-responsive system, consisting of core/shell bi-magnetic nanoparticles with furan surface functionality, is bonded with N-(2-Carboxyethyl)maleimide through Diels-Alder reaction. The chemotherapeutics doxorubicin is attached onto the surface, with a high loading efficiency of 92%. This system with high responsiveness to a high frequency external alternating magnetic field shows a very good therapeutic efficiency in hyperthermia and drug release at relatively low temperatures (50°C). Polyhedron-shaped bi-magnetic nanoparticles (Zn
