"BIOSENSOR: Process quickly, cheaply yields microfluidic chips"
A faster, less expensive way to prototype microfluidic chips has been developed at Purdue University. For just a few dollars, the tiny chips--which sense potential toxins in molecule-sized samples--can now be fabricated in hours, not weeks, and at room temperature instead of in vacuum ovens. The method developed at Purdue (West Lafayette, Ind.) mates specially selected and prepared nanoscale "wicks" with easy-to-assemble polymer deposition. The chips and the postage-stamp-sized analytic devices made with them have potential applications in food safety, biosecurity, clinical diagnostics, pharmaceuticals and electronics, according to the researchers.
