摘要:
A thermosensitive nanostructure for hyperthermia treatment. Magnetic nanoparticles are encapsulated in a thermosensitive polymer nanostructure having a lower critical solution temperature (LCST) of about 40-45° C. The thermosensitive polymer nanostructure may carry a drug. When the magnetic nanoparticles are heated to 40-45° C. by application of an alternating magnetic field in hyperthermia treatment, the thermosensitive polymer nanostructure collapses to release the drug, thus providing concurrent drug treatment.

摘要:
A core-shell structure with magnetic, thermal, and optical characteristics. The optical absorption band is tailorable by choice of the mixing ratio of the core/shell component to give the desired shell thickness. The core-shell structure is particularly suitable for biomedical applications such as MRI (magnetic resonance imaging) developer, specific tissue identification developer, and magnetic thermal therapy.
