There are 6.1 million lead service lines in United States and this fact leaves many Americans in a precarious situation, as slight changes in the properties of their water, such as pH, could result in the leaching of lead into their tap water. Unfortunately, current technologies for lead detection are expensive and require trained personnel. To address this issue, we propose a simple and inexpensive paper test for lead(II) in tap water, where polymer nanoparticles, which encapsulate a molecular probe that has a colorimetric response to lead(II), will be anchored at the test line of a lateral flow assay (LFA). As a tap water sample flows down this paper strip, if lead(II) in present, a signal will result from the interaction of the lead(II) ions with the molecular probe. The test will result in a signal that can be visually observed and interpreted by the user, giving communities which fall victim to contaminated water the opportunity to test their water and have control over their health.
