The reporter learned from the Science and Technology Department of Yangzhou University that the school's College of Chemistry and Chemical Engineering successfully developed a new bioelectrochemical detection chip, the core of which is a bioelectrochemical sensor based on polymer self-assembled film, which will make the detection of cancer cells change. It is as simple as a blood glucose meter to check for early prevention of cancer.

At present, the commonly used body fluid testing methods in major hospitals in China are immunofixation electrophoresis, which has high detection cost, strict equipment requirements and long detection time, which makes a large number of patients lose the golden period of treatment of diseases. "Our research team will secrete a very small amount of monoclonal globulin and free light chain in the early blood of patients, and the antibody that recognizes this protein will be grafted on the polymer microporous membrane matrix on the surface of the electrode. A recognition, with the help of the electrochemical workstation, zoomed into a chemical signal, successfully achieved the function of examining cancer cells in the early stage of the disease," said Wang Tianyu, the person in charge of the project.

This technology is currently undergoing clinical trials at the People's Hospital of Jiangsu Province, Jiangsu Province. From sample collection to injection, testing and medical analysis, it takes only 10 minutes, and the cost is low and the accuracy is good. Compared with the immunofixation electrophoresis method commonly used in hospitals, the detection sensitivity is improved by 500 times. Not only that, the cost of the testing equipment for this technology is only 80,000 yuan, which reduces the access to inspection and can be widely used in small and medium-sized cities and remote areas.
