Fluorescein molecules are extensively used to develop fluorescent probes for various
analytes due to their excellent photophysical properties and the spirocyclic structure. The …

Background: Water is polluted daily with biological and chemical toxins that can seriously
threaten human health, animals and ecosystems. The regular identification and monitoring …

Heavy metal ion pollution harms human health and the environment and continues to
worsen. Here, we report the synthesis of boron (B), phosphorous (P), nitrogen (N), and sulfur …

A novel fluorescent chemosensor PS founded on rhodamine 6G for Hg 2+ has been
synthesized and authenticated by employing 1 H NMR, 13 C NMR, and LC–MS skills. The …

Copper ion is closely associated with the ecosystem and human health, and even a little
excessive dose in drinking water may result in a range of health problems. However, it …

A novel Schiff base probe N'-(2-hydroxybenzylidene)-5-(naphthalen-1-yl) oxazole-4-
carbohydrazide (G1) was designed and prepared based on a condensation of 5 …

Organic dye-based nanoparticles (ODNPs) are fabricated with desired morphologies using
laser ablation, reprecipitation, ion association, and self-assembly methods. Primitively, this …

Carbon dots have drawn extensive attention in the detection of metal ions with good stability,
excellent biocompatibility and low toxicity. Meanwhile, the quantum yield, response rate and …

Fluorescein itself is a synthetic organic compound and a prominent member of the xanthene
dye family. It exhibits strong fluorescence under ultraviolet (UV) or blue light excitation …

Developing carbon quantum dots (CQDs) from bio-waste lignin for effectively detecting Cu
2+ is of great significance for promoting the value-added utilization of lignin resources …
