Abstract

The invention discloses an activated carbon nanosphere which is prepared by taking activated carbon particles with the particle sizes of 10-100nm as carriers, and the surfaces of the activated carbon particles are compounded with an organic dyestuff. The activated carbon nanosphere disclosed by the invention is rather strong in dyeing property, remarkable in tracing effect and capable of remarkably showing a lymph tracing effect for a tested living body within half a hour, realizing multi-mode imaging and directly observing the trace of the nanosphere from tumors, tissues or organs through naked eyes.

Description

technical field [0001] The invention relates to a nano particle, in particular to a composite nano particle prepared with activated carbon as a carrier, and the application of the nano particle in determination of tumor boundaries and lymph node metastasis tracing. Background technique [0002] At present, there are nearly 3 million cancer deaths in my country every year, and surgery is still the first choice and the most effective treatment. However, the postoperative survival rate at home and abroad has remained at a low level. Taking gastric cancer as an example, the postoperative 5-year survival rate is mostly hovering at 20-30%. A big reason is that the lymph nodes were not completely removed during the tumor resection, and the infiltrating tumor cells passed through the lymphatic vessel wall and transferred along the lymphatic vessel with the lymph fluid, causing the patient to relapse or metastasize and die within a short period of time after surgery.
