Description

technical field [0001] The invention relates to the technical field of tumor detection, in particular to a peripheral blood circulating tumor cell detection chip and system based on radio frequency wireless detection technology. Background technique [0002] Circulating tumor cells refer to tumor cells that fall off from tumor tissues and enter peripheral blood. A large number of research data have confirmed that the rapid detection of circulating tumor cells in blood has important application value for tumor detection, individualized treatment, curative effect evaluation and prognosis monitoring. Compared with traditional imaging and pathological tumor diagnosis methods, the detection of circulating tumor cells has unique advantages. First of all, the circulating tumor cell detection method can simultaneously screen most multiple solid tumors such as lung cancer, gastric cancer, and liver cancer at one time, and has a larger detection range. At the same time, only blood te...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing detection methods based on circulating tumor cells generally use enzyme-linked immunosorbent assay or polymerase chain reaction, which often require harsh experimental conditions, relatively expensive experimental equipment and reagents.
