translated from Spanish: They create a chip that can detect cancer early

Early detection of cancer is what a chip has achieved by a group of scientists from the Worcester Polytechnic Institute (USA). Specifically, they have been able to identify breast and lung cancers prematurely.
The function of the chip is to capture circulating tumor cells (CTCs) in a blood sample. The innovative thing about the device is that it is equipped with carbon nanotubes, where CTCs adhere.
Tests on blood samples from breast cancer patients obtained a 100% sensitivity rate for CCD.
“This could be an annual test done in your doctor’s office. We have the potential to improve (test) sensitivity enormously,” research leader Balaji Panchapakesan told the Telegram portal.

“To travel to a distant location in the body and start a new tumor, CTCs need the ability to adhere in an environment that is not conducive to adhesion. In previous research, we have shown that they adhere preferably to carbon nanotubes, but that white blood cells do not, in general,” scientists told Europa Press.
The chip, unlike other similar methods, completely separates tumor cells from white blood cells in the sample. According to Panchapakesan, this rules out the possibility of confusing both.
Although the source reason for using the device has been cancer screening, its use can also be expanded to other medical areas. With the chip, for example, Down syndrome could be detected from fetal cells, Panchapakesan explained.
The team is still testing with the chip. Therefore, it is currently not possible for the device to enter the market, although some companies have already expressed interest in the product.
