Abstract

The invention provides a nickel doped copper sulfide nano material. The chemical general formula of the nickel doped copper sulfide nano material is Cu1-xNixS, wherein CuS refers to a substrate, Ni<2+> refers to doping ions, and the value range of x is that x is larger than 0 and is smaller than or equal to 0.8; the nickel doped copper sulfide nano material provided by the invention is a multifunctional nano material and simultaneously has a magnetic resonance imaging function and a photothermal therapy effect, so that the nickel doped copper sulfide nano material can be used as a magnetic resonance imaging probe and a photothermal therapy reagent and is a nano material integrating detection and therapy. The invention further provides a preparation method and an application of the nickel doped copper sulfide nano material.

Description

technical field [0001] The invention relates to the field of medical nanomaterials, in particular to a nickel-doped copper sulfide nanomaterial and its preparation method and application. Background technique [0002] In recent years, the morbidity and mortality of cancer have been increasing, and it has become one of the most challenging medical problems in the 21st century. Early investigation, early diagnosis, and early treatment are effective ways to treat tumors. However, normal tissue is often indistinguishable from early diseased tissue. Among the existing imaging techniques, magnetic resonance imaging can display physiological and anatomical details to a certain extent without ionizing radiation. It is the most effective non-invasive imaging technique and is widely used in clinical medicine. Using magnetic resonance imaging to image the tumor can judge the main outline of the tumor before the operation and achieve the purpose of preoperative guidance. [0003] In ...
