New method allows more complex paper tests
from Laboratory Equipment
Researchers have invented a technique that uses inexpensive paper to make "microfluidic" devices for rapid medical diagnostics and chemical analysis. The innovation represents a way to enhance commercially available diagnostic devices that use paper-strip assays like those that test for diabetes and pregnancy. "With current systems that use paper test strips you can measure things like pH or blood sugar, but you can't perform more complex chemical assays," says Babak Ziaie, a Purdue University professor of electrical and computer engineering and biomedical engineering."
