The study successfully prepared a waterdispersible chlorophyll-based fluorescent material and constructed a sensing system for highly sensitive and selective detection of Cu2+ and biothiols.
The environmental risk of artificial synthetic dyes sparked interest in exploring high-security fluorescent materials for suitable analysis applications. Chlorophyll-based fluorescent material is a good candidate but subjects to inferior dispersibility and low fluorescence efficiency in water. In this work, we successfully prepared a waterdispersible chlorophyll-based fluorescent material through simple solvent extraction of willow seeds. Compared to other conventional sources of chlorophyll, such as willow leaves, metasequoia, and green algae, only the chlorophyll-based material from willow seeds (C-WS) can retain good near-infrared fluorescence performance with an emission wavelength of 677 nm in the water phase, which can promote the practical application of chlorophyll-based fluorescent materials. An on-off-on sensing system was constructed based on C-WS for the highly sensitive and selective detection of Cu2+ and biothiols in aqueous solution. The limit of detection for Cu2+ and GSH can reach 1.2 nM and 92 nM, respectively. Furthermore, the proposed system was successfully used in the detection of Cu2+ in real water samples and biothiols in food samples, and successfully applied for the visualization of intracellular Cu2+ and biothiols in Hela cells.
