Blood tests on a CD player?
16 October 2000
Research at the Ohio State University in the US is paving the way for doctors to conduct blood tests using a CD and CD player and, one day, patients may be able to own a CD that can analyse drops of their own blood.
Professor of Materials Science and Engineering at the university, Professor Marc Madou described his latest research at the recent Eurosensors XIV conference in Denmark.
With a team of researchers, Professor Madou is perfecting the shape of tiny reservoirs and channels on the surface of a CD to allow medical samples and other chemicals to mix while the disc spins.
Once perfected, the disc could measure glucose levels in people with diabetes and store that information, it could measure the concentration of potassium or sodium and could also be used in the discovery of new drugs.
