Excessive copper (as Cu(II)) in drinking water-in place through mining, farming, manufacturing operations, and municipal or industrial wastewater releases-can be a threat to human health and ecosystem wellbeing. Some sources of drinking water are remote; hence, the sensitive, selective, and portable detection of contaminated copper in drinking water sources is of great importance. Through this work, a portable fabric amperometric nanosensor has been devised via a simple dip-coating method, which is able to rapidly, sensitively, and selectively detect Cu(II) ions in a range of 0.65 to 39 ppm in real time. The prepared Cu(II) nanosensor, which operates under a low voltage, consists of three layers: electrospun nylon-6 nanofibers, multi-walled carbon nanotubes, and 2,2:5,2 '' -terthiophene molecules. Potential interfering metal ions, including Cd(II), Fe(II), Pb(II), Hg(II), and Ag(I) ions, have no significant influence on the response of the Cu(II) nanosensor. This fabric sensor-that is able to be placed in your pocket and carried about-is more portable than current technologies, while being able to detect Cu(II) on the same level necessary for potable water. We anticipate our nanosensor to be a starting point for more sophisticated and comprehensive heavy metal assay. Furthermore, this nanosensor will aid in on-site detection of Cu(II) in potential drinking water sources, lending itself well to third world and remote detection. A polymer nanocomposite sensor has been developed for the sensitive and selective detection of copper in water.
