The recognition and detection of metal ions present in biological and environmental samples have attracted great attention in recent years. Various analytical techniques are used to detect metal ions. Among these, the fluorescence technique is among the emerging methods because of its simplicity, selectivity, and applicability to bioimaging. Thus, this review particularly explores paper-based fluorescence chemosensors involved in metal ion detection. Significantly, the first section addresses relevant research on metal ion detection involving various techniques. In the second section, several sensing strategies such as photoinduced electron transfer, fluorescence resonance energy transfer, intramolecular charge transfer, chelation enhanced fluorescence, excited-state intramolecular proton transfer, and aggregation-induced emission for the detection of target metal ions (aluminum, copper, iron, lead, mercury, and zinc) are investigated. The third section particularly discusses the role of fluorescence sensor materials (e.g., fluorescein, rhodamine, naphthalimide, BODIPY, carbon dots, quantum dots) involved in the detection processes and their advantages and limitations. Overall, this article reviews 90 research articles on paperbased fluorescence chemosensors for metal ion detection published until 2021.

“…[11,12] Based on our experiences and references, in Schiff base structure, the nitrogen in carbon nitrogen double bond is easily complexed with metal ions. [13][14][15] Benzoyl hydrazine moiety could act as electron withdrawing group, which could easily interact with metal ions and other electron-deficient systems by donor-acceptor interaction. [16,17] To improve the fluorescence performance and sensitivity, coumarin was chose as fluorescent group and a large conjugated structure was constructed using Schiff base unit (C=N) as linker.…”

In this paper, two dual function fluorescent probes P1 and P2 with obvious fluorescence spectrum change were developed for the detection of Zn2+ and H2S. Density functional theory (DFT) was employed to investigate the detection mechanism. A further illustration of the fluorescence quenching mechanism was also studied by 1H NMR titration and UV‐Vis absorption spectroscopy. Both probes are new compounds containing coumarin structure as fluorophore. They can quantitatively detect Zn2+ and H2S in the concentration range from 0 to 50 μM with excellent selectivity and anti‐interference ability over many metal ions or anions. Most worthy is that probes P1 and P2 have better cell permeability with lower cytotoxicity, which can be used for fluorescence detection in MCF‐7 cells, as well as the detection of exogenous Zn2+ in organisms.
