A few days ago, researchers at Tel Aviv University in Israel made a colon cancer detection chip based on "chip lab" technology, which can be detected only by the patient's body fluid, which can greatly improve the diagnosis rate of colon cancer.
It is understood that this study was carried out by Safir Vinike, Department of Physics and Electronics, Tel Aviv University, Israel. According to Vickel, if this test method is combined with several traditional detection methods, the diagnosis rate of colon cancer will be greatly improved. Their ultimate goal is to enable patients to test in their own homes, and doctors can judge the condition through the Internet.
According to reports, the "chip lab" solution is similar to the widely used pregnancy test and blood glucose level test, by which the patient's biomarker can be detected. According to reports, biomarkers of colon cancer are widely present in the blood, urine or other body fluids of patients, either by the tumor itself or by the body after cancer. The chip is mainly composed of an electrochemical biosensor, which is programmed to be extremely sensitive to such biomarkers. When a corresponding substance is detected, the electrodes on the chip emit a signal for measurement. "Chip Lab" technology is a micro-full analysis system based on the chip, which can transfer the basic functions of the analytical laboratory to a chip of several square centimeters, thus completing sample preparation, biological and chemical reactions. Basic operations such as separation and detection. The ultimate goal is to personalize and personalize the analytical laboratory.
Colon cancer is a common malignant tumor of the digestive tract. The predilection site is the junction of the rectum and the rectum and the sigmoid colon. The incidence of 65% is more than 40 years old. According to the American Cancer Society, colon cancer has become the third largest cancer in the United States, and colon cancer is the most easily diagnosed in the three cancers. Nearly one-third of colon cancer deaths can be avoided by early treatment. . Early symptoms of colon cancer are mild or inconspicuous, often overlooked by patients, and easily missed. In the late diagnosis, it is necessary to first remove the intestinal polyps and conduct a large number of laboratory evaluations, even for several weeks. In terms of detection means, although the conventional endoscopy method is highly effective, it will cause great pain to the patient, and other diagnosis methods are not only time-consuming but also inaccurate.

Auxiliaries (Additives) are defined in medicine as excipients and additives used in the production of drugs and prescriptions, that is, all materials except the main active ingredients of drugs, are important components of pharmaceutical preparations. In industrial production, auxiliary chemicals added to improve the production process, improve product quality and yield, or to endow the product with a specific application performance. It is also called additive. However, as an important component of the product matrix, large doses of additives, which have a significant impact on the shape, structure and performance of the product, are generally not included in the category of additives.
