TL;DR: In this article, water-soluble and blue fluorescent carbon dots (C-dots) were synthesized using one-pot hydrothermal method with malonic acid and urea, and were then used as a label-free fluorescent probe for selective, sensitive, and rapid determination of picric acid (PA).

TL;DR: A stable silver nanoparticles/carbon quantum dots (Ag/CQDs) composite was prepared by using CQDs as reducing and stabilizing agent, and exhibits a good selectivity toward Hg2+ over other metal ions.

TL;DR: Water-soluble nonconjugated polymer nanoparticles (PNPs) with strong fluorescence emission were prepared from hyperbranched poly(ethylenimine) and d-glucose via Schiff base reaction and self-assembly and developed as a fluorescent probe for fast, selective, and sensitive detection of nitro-explosive picric acid in aqueous medium.

TL;DR: This work synthesized boron and nitrogen co-doped carbon dots (B,N-CDs) by one-step hydrothermal method using 3-aminophenylboronic acid as the sole precursor and showed the practicability of p-NP determination in environmental water samples.

TL;DR: A bidimensional optical sensing platform which combines the advantages of fluorescence and colorimetry has been designed for arginine (Arg) detection and revealed excellent selectivity toward Arg over other amino acids.
