Microfluidic Paper-Based Analytical Device for Aerosol Oxidative Activity [PDF]
Environmental Science & Technology, 2012 Human exposure to particulate matter (PM) air pollution has been linked with respiratory, cardiovascular, and neurodegenerative diseases, in addition to various cancers. Consistent among all of these associations is the hypothesis that PM induces inflammation and oxidative stress in the affected tissue.

Microfluidic Paper-Based Analytical Device for the Determination of Nitrite and Nitrate [PDF]
Analytical Chemistry, 2014 A low-cost disposable colorimetric microfluidic paper-based analytical device (μPAD) was developed for the determination of nitrite and nitrate. Nitrite is determined directly by the Griess reaction while nitrate is first reduced to nitrite in a hydrophilic channel of the μPAD with immobilized zinc microparticles.
