A Novel Synthesis of FeO@SiO@Au@Porous SiO Structure for NIR Irradiation-Induced DOX Release and Cancer Treatment
Doxorubicin (DOX) alone or in combination has been widely used for numerous cancers, including breast, lung, bladder, and so on. In this article, a core/shell/shell structured Fe 3 O 4 @SiO 2 @Au@porous SiO 2 particles for the drug delivery and release of DOX was demonstrated, with the aid of near-i...

Fe 3 O 4 was used to direct the transportation and delivery of the drug-loaded composite to the target tissues and organs under an external magnetic field, the first layer of SiO 2 was used for Au nanoparticle attachment, Au acted as the agent for light–thermal conversion, and the porous SiO 2 was used to load DOX.
