HIV testing in developing nations

The device, which uses silicon micro-fabrication, allows blood cells and platelets to pass through while the large white blood cells are captured and counted.

University of Michigan scientists are developing a device using nanofabrication that would more effectively analyze a blood sample to test for HIV in the developing world. The device, which uses silicon micro-fabrication, has 10,000 micro-holes that act as craters, allowing the blood cells and platelets to pass through while the large white blood cells are captured and counted.

ABOUT THE SCIENTISTS: The team involved in the project include Associate Professor of Mechanical, Biomedical and Macromolecular Science and Engineering Nikos Chronis, as well as engineering PhD student Anurag Tripathi and Dr. James Riddell, an infectious disease specialist at the U-M Department of Internal Medicine.
