New blood test leads to early disease diagnosis
A University of Virginia chemistry professor has created a device that he says can very quickly diagnose certain diseases at the earliest stages of onset.
University of Virginia's James Landers told Earth & Sky that this device - which resembles a glass microscope slide - uses nanotechnology. It works by analyzing the patient's blood. Tiny, nanoscale pores embedded in the device allow it to examine DNA molecules in the blood for signs of disease.
