A reusable nanofibrous film chemosensor for highly selective and sensitive optical signaling of Cu2+ in aqueous media†
Abstract
A novel surface modification strategy for an electrospun nanofibrous film was reported, allowing detection and removal of copper ions in the aqueous solution. This reusable dual fluorescent–colorimetric nanofibrous film can be utilized conveniently to achieve real-time naked-eye sensing in aqueous medium just like using a test paper.
