    摘要: The invention discloses the synthesis and manufacturing of a novel core-shell nano-carrier with a drug-containing nanocomposite core surrounding with a single crystalline magnetic iron oxide shell. With a unique core-shell configuration, active agents such as drugs and biomolecules encapsulated in the core with an outer single-crystalline thin iron oxide shell can be perfectly protected from environmental damages and in the meantime, eliminating un-desirable release due to un-controllable diffusion of the active molecules from the nanocapsules during the course of delivery in patient's body, before reaching the disease sites.

    摘要: Nanodevice and method for in vivo monitoring and release of drugs are provided. The disclosed nanodevice is characterized in having a drug-loaded nanosphere that is capable of releasing the encapsulated drugs upon magnetically stimulation. The nanodevice may also be used as a contrast agent for in vivo imaging and monitoring the concentration and distribution of the released drugs and/or active compounds injected separately into a target site of a subject.
