Polymeric nanofiber-based ion-selective sensors

Ion-selective sensors are established tools of chemical analysis used in both electrochemical and optical sensing modes. They allow insight into ion concentrations in various samples, offering reliable performance. One of the ways of improving this class of devices is to explore the benefits of nanoscale receptor layers. In this respect, nanofibers seem to be a highly attractive option because of unique properties related to the geometry of this class of nanomaterials. This paves the way to explore alternative approaches to design ion-selective receptors architecture, to benefit from receptor molecules that are not compatible with classical ion-selective membranes
