Increasing reaction temperature produces photoluminescent polymer nanodots (PPNDs) with decreased particle size and increased quantum yield. Such PPNDs are used as an effective fluorescent sensing platform for label-free sensitive selective detection of Cu(II) ions a limit low 1 nM. This method is successfully applied to determine Cu(2+) in real water samples.
The present article reports on a simple, economical, and green preparative strategy toward water-soluble, fluorescent carbon nanoparticles (CPs) with quantum yield of approximately 6.9% by hydrothermal process using low cost wastes pomelo peel as source for the first time. We further explore use such CPs probes Hg(2+) detection application, which is based Hg(2+)-induced fluorescence quenching CPs. This sensing system exhibits excellent sensitivity selectivity Hg(2+), limit 0.23 nM achieved....
In this work, we develop a novel environmentally friendly strategy toward one-pot synthesis of CuS nanoparticle-decorated reduced graphene oxide (CuS/rGO) nanocomposites with the use L-cysteine, an amino acid, as reducing agent, sulfur donor, and linker to anchor nanoparticles onto surface rGO sheets. Upon visible light illumination (λ > 400 nm), CuS/rGO show pronounced enhanced photocurrent response improved photocatalytic activity in degradation methylene blue (MB) compared pure CuS. This...
In this contribution, we demonstrate a green, cost-effective, one-pot preparative route toward Ag nanoparticles-graphene (AgNPs–G) nanocomposites in aqueous solution with the use of tannic acid (TA), an environmentally friendly and water-soluble polyphenol, as reducing agent.

Graphene quantum dots (GQDs) have been widely used as fluorescence probes to detect metal ions with satisfactory selectivity. However, the diverse chemical structures of GQDs lead selectivity for multiple ions, and this can trouble in interpretation due lack an depth systematic analysis.

Specifically, we demonstrated coordination...
Surface-enhanced Raman scattering (SERS) is expected as a technique that even theoretically detected chemicals at the single molecule level by surface plasmon phenomena of noble metal nanostructures. Insensitivity detecting weak-intensity molecules and low adsorptivity gaseous on solid substrates are two main factors hindering application SERS in gas detectors.
