Virgin silver nanoparticles as colorimetric nanoprobe for simultaneous detection of iodide and bromide ion in aqueous medium

Electroanalytical Sensing of Bromides Using Radiolytically Synthesized Silver Nanoparticle Electrocatalysts

“…It should be noted that higher sensitivity with Ag electrodes studied herein could be obtained using more sensitive electroanalytical methods (such as square wave voltammetry, differential pulse voltammetry, and chronoamperometry) and with optimisation of operational parameters. Still, the LOD value obtained at pure Ag catalyst was somewhat higher or comparable with LODs obtained using different Ag-based catalysts for bromide sensing reported in the literature (LODs in 1.2–22 μ M range) [ 23 – 29 ]. For example, Compton et al reported LOD for bromides of 3 μ M at AgNPs-GC-epoxy composite electrode and of 22 μ M at GCM-Ag/MWCNT/GCE (Glassy Carbon Metal, Multi Wall Carbon Nanotube, Glassy Carbon Electrode) [ 8 , 25 ].…”

DNA‐Templated Copper Nanoprobes: Overview, Feature, Application, and Current Development in Detection Technologies

“…Iodine plays an important role in the human body and is the primary constituent of thyroid hormones . The iodide (I − ) has concentration‐relation to the early stage monitoring of the corresponding health problems . An iodide ion detection method was developed by using ssDNA‐templated Cu‐NPs as the fluorescent probe (Figure (B)) .…”

“…[34] The iodide (I À ) has concentration-relation to the early stage monitoring of the corresponding health problems. [35] An iodide ion detection method was developed by using ssDNA-templated Cu-NPs as the fluorescent probe (Figure 3(B)). [36] Iodide ions can instantly quench the fluorescence of ssDNA-templated Cu-NPs and can thus be quantified (linear range 0.050 to 40 μM and 40 to 80 μM).Limit of detection of this method was as low as 15 nM.…”

The use of S2O82− and H2O2 as novel specific masking agents for highly selective “turn-on” fluorescent switching recognition of CN− and I− based on Hg2+–graphene quantum dots

“…These disorders can be prevented by ensuring optimal iodide intake. 28,29 With regard to cyanide, it is the most threatening to the environment and human life. Various products are very high in cyanide due to their industrial uses, including the production of paper, textiles, plastics and nitriles, metals, electroplating and the extraction of gold and silver.…”
