Preparation method of multi-mode rhenium disulfide diagnosis and treatment agent

The invention discloses a preparation method of a multi-mode rhenium disulfide diagnosis and treatment agent, which comprises the following steps: respectively putting liquid bromine, rhenium and sulfur into a quartz tube, and heating to obtain blocky single crystal ReS2; the preparation method comprises the following steps: grinding blocky single crystal ReS2 into powder, and mixing the powder with a nitric acid solution to form a mixed solution; the mixed solution is stirred and then centrifuged, a sample is cleaned, and a ReS2 micron layer with magnetism is obtained; dispersing the obtained ReS2 micron layer into a mixed solution of N-methyl pyrrolidone and ethanol, centrifuging and cleaning to obtain a ReS2 nano layer; the obtained ReS2 nano layer and an mPEG-NH2 solution are mixed, stirred and dried, and the mPEG-NH2 modified ReS2 nano layer is obtained. The diagnosis and treatment agent obtained by the invention not only improves the definition and sensitivity of human soft tissue imaging, but also has
