The presence of, or changes in the concentration of, certain proteins in biological fluids can be indicators of disease. (sciencedaily.com)
But detecting very small amounts of it in blood and other biological fluids can be difficult for health researchers, especially in the limited amounts available in laboratory experiments. (sciencedaily.com)
Going forward the group plans to test the device in a more complex set - up, for example with an actual biological fluid like urine that has many dissolved components. (sciencedaily.com)
