Abstract

The invention relates to a preparation method of flaky Cu9Fe9S16 nanoflowers. The preparation method includes dispersing a ferric salt and a manganese salt into a solvent with stirring, adding trisodium citrate dihydrate with stirring, adding sodium acetate with mixing uniformly, performing solvothermal reaction for 6-8 hours at 180-240 DEG C prior to centrifuging and washing so as to obtain Fe2MnO4 nanocrystalline; dispersing the Fe2MnO4 nanocrystalline into water, adding a (NH4)2S solution, conducting ultrasonic dispersion and centrifugal washing, and dispersing a product into water so as to obtain dispersion liquid; adding a copper salt solution into the dispersion liquid, and conducting ultrasonic dispersion and centrifugal washing so as to obtain the flaky Cu9Fe9S16 nanoflowers. The preparation method has the advantages of simplicity, safety, environment friendliness, low cost and easiness in operation. The flaky Cu9Fe9S16 nanoflowers are capable of effectively converting near-infrared light into heat and have a nuclear magnetic imaging effect, thereby being quite promising in application prospect for photothermal therapy and diagnosis of cancers.

Description

technical field [0001] The invention belongs to the field of preparation and application of photothermal conversion materials, in particular to a flaky Cu 9 Fe 9 S 16 Preparation method of nanoflowers. Background technique [0002] Photothermal ablation therapy, as an emerging method for the treatment of cancer, has received extensive attention in recent years. It is particularly important to choose a suitable light-to-heat conversion material. At present, there are four main categories of light-to-heat conversion materials: metal-based light-to-heat conversion materials, carbon-based light-to-heat conversion materials, organic compound light-to-heat conversion materials, and semiconductor light-to-heat conversion materials. Semiconductor light-to-heat conversion materials have been greatly developed due to their low price, good stability, high light-to-heat conversion efficiency, and adjustable absorption spectrum. [0003] Especially a class of ternary compounds based...
