The Australian research team invented a biochip that separates cancer cells from the blood, identifying cancer cells in the blood and removing them. This technology can significantly reduce the cost of cancer treatment and is expected to prolong the lives of patients.
The biochip, developed by a research team at the University of New South Wales in Australia, filters blood in a device called "Cancer Dialysis" to screen and remove cancer cells. The team's original intention in developing this chip was to find a cheaper and less painful way to diagnose cancer.
Dr. Majid Valkiani, the head of the team, said that 99% of cancers in human cancers are solid tumors, and cancer cells that enter the human peripheral blood (except blood other than bone marrow) will spread to the body along with blood. Other parts. According to the characteristics that cancer cells are larger than healthy cells and have higher metabolism, doctors put blood mixed with healthy cells and cancer cells into biochips. Under the influence of fluid pressure, larger cancer cells and smaller healthy cells are respectively Enter different outlets and successfully separate.
The chip also significantly reduces the cost of treatment associated with cancer. It is understood that the cost of scanning for cancer testing in Australia is about 700 Australian dollars (about 3229 yuan), and the cost of using this chip to detect cancer cells in the blood is only 50 to 100 Australian dollars (about 230 yuan to 460 yuan).
In addition, the technology may extend the lives of cancer patients. Some doctors have suggested that if a large chip can be made, the blood of a cancer patient will be "cleaned" just like kidney dialysis. The blood from which the cancer cells have been separated is returned to the patient, and the immune response caused by the blood of other people is also avoided. For patients with early cancer, this technique can reduce the risk of cancer metastasis.
