Selective and sensitive detection of aqueous contaminants via coinage metal-enhanced fluorescence with diiminic Schiff bases

Role of transition metals in coinage metal nanoclusters for the remediation of toxic dyes in aqueous systems

“…Chinta et al 14 summarized colorimetric tests for natural amino acids using coinage metal nanoparticles. Sharma et al 15 reviewed coinage metal-enhanced uorescence using diiminic Schiff bases for the selective and sensitive detection of aqueous pollutants. Similarly, metal nanocluster-based luminescent biosensors via etching chemistry were reviewed by Si et al 16 Nanostructures are classied into nanoparticles (PNls) and nanoclusters (CNs) depending on their size.…”

Analytical developments in the synergism of copper particles and cysteine: a review

“… 21 Multiplex detection, which refers to the ability of a sensor to detect numerous analytes, is also possible. Some sensors depend on a “turn-off” or “on/off” mechanism, which detects analytes by producing a signal as well as turning them on or off when there is a decline in a signal 22 [ Fig. 2 ].…”

“…Copper is the most significant contender in this category because of its availability and affordability. 22 …”
