Researchers Create Lab-on-Chip Using Low-Cost Paper Strips

January 27, 2011 – 5:29 pm

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. “This new approach offers the potential to extend the inexpensive paper-based systems so that they are able to do more complicated multiple analyses on the same piece of paper. It’s a generic platform that can be used for a variety of applications.”
