Abstract

Paixão and Hashemi propose to combine synergies and to produce a one-of-a-type paper-based device for fast trace analysis in-situ, applied to environmental systems and even biological systems (blood tests). The initial work, proposed below, will yield prototype devices that the PIs propose to a) use as preliminary work towards larger grant applications and b) commercialize. (AU)
