Functionalized-tryptophan stabilized fluorescent Ag nanoclusters: Synthesis and its application as Hg2+ ions sensor

Gum acacia-based silver nanoparticles as a highly selective and sensitive dual nanosensor for Hg(ii) and fluorescence turn-off sensor for S2− and malachite green detection

“…7 To overcome these disadvantages, researchers have developed optical methods such as colorimetric, uorescence, surface plasmon resonance, and surface-enhanced Raman scattering for the detection of mercury. 8 Fluorescence spectroscopy and colorimetric method have surpassed the above-mentioned methods owing to their high sensitivity and selectivity, fast analysis, and less complicated experimental procedures. 9,10 Noble metal nanoparticles such as gold and silver have aroused a great deal of recognition because of the optical phenomenon called 'Surface Plasmon Resonance' exhibited by them.…”

Green Synthesis of Fluorescent Ag Nanoclusters for Detecting Cu2+ Ions and Its “Switch-On” Sensing Application for GSH

“…e peaks at 398 eV, 400 eV, and 408.1 eV shown by red line, green line, and blue line were attributed to C-N, N-H, and -NO 2 . e peak that appeared at 408.1 eV showed that some of the amino groups of L-histidine reduced Ag + to Ag 0 and the amino groups were oxidized to -NO 2 groups [26].…”

“…e Ag NCs synthesized with different stabilizing ligands such as DNA, protein, peptide, and amino acid possess different optical properties and application areas [21][22][23][24][25][26].…”

Two-dimensional FeS nanoflakes: synthesis and application to electrochemical sensor for mercury(II) ions

“…detection methods that are cost-effective, rapid, sensitive, and selective. In consideration of these, researchers have developed a number of chemical methods, such as surface plasmon resonance (Jorn et al 2004), surface-enhanced Raman scattering (Duan et al 2012), colorimetric assay (Shi and Ma 2008;Zhou et al 2014), fluorescence spectrometry (Bian et al 2014), and electrochemical sensors for the detection of Hg 2? ions.…”
