The invention relates to a self-temperature-control
magnetic nanowire and s preparation method thereof, and belongs to the technical field of tumor magnetic induction thermotherapy. In order to solvethe problems of low heat
production rate and agglomeration of
magnetic nanoparticles, the invention provides a preparation method of a self-temperature-control
magnetic nanowire. The preparation method comprises the following steps:
anodizing an
aluminum foil to prepare an aluminum anodized micro-channel template, depositing
zinc-
cobalt-
chromium ferrite
hydroxide in the micro-channel template by using a chemical
coprecipitation method, performing
sintering to form a
zinc-
cobalt-
chromium ferrite
magnetic nanowire, and carrying out surface hydrophobization treatment on the magnetic
nanowire. Theself-temperature-control magnetic
nanowire prepared by the invention has the
diameter of 5-45nm, the length of 5-30mu m and the
Curie temperature point of 42-45 DEG C, is stable in chemical propertyand excellent in magnetic property, has the
Curie point temperature meeting the
magnetic hyperthermia requirement, has the advantages of
high heat yield, low possibility of agglomeration, good performance consistency and good
biocompatibility, and can be used for
batch production of magnetic nano media and magnetic hot seeds for
magnetic hyperthermia.
