Part of the war against HIV is to invest in early detection of the virus. However, in many countries around the world, patients go to qualified hospitals for testing and testing, and often need to wait for hours to obtain diagnostic results. Recently, however, scientists at the University of Illinois and Daktari Diagnostics have teamed up to create a portable solution for detecting HIV viruses – business card-sized biochips. This small chip not only scans for HIV, but also accurately displays the total number of T cells.
The ultra-thin microfluidic carrier developed by the researchers is a lab chip. This chip can handle a small amount of fluid material, such as a drop of blood. When blood is dripped into the chip, the white blood cells are shunted into a protein-filled chamber that has sensors built in to count T cells. In this way, the doctor will be able to check if the blood is HIV positive. In general, patients with HIV have lower levels of T cells in their blood than those in healthy people. The chip is placed in a battery-powered micro device to read the results.
The successful development of this chip enables the world's most poor areas to diagnose and monitor HIV more quickly, which is more convenient for current HIV testing procedures, and it is more than what is used in the market. HIV testing methods are cheaper. Based on such a chip, the mobile device that reads the data costs about $1,000, and the test itself is only around $10. The R&D team has planned to commercialize this technology and will soon be testing in this area. Of course, curing HIV may be better news, but the rapid diagnosis before this can also save lives in time through technology.
Scientists hope to further expand the functionality of this biochip. Although it can detect the number of white blood cells, it may also have potential infections.
