A highly selective SERS chip for rapid detection of copper ions in aquatic system

Cu(i)-catalysed 1,2,3-triazole stitched chalcomer assembly as Pb(ii) and Cu(ii) ion sensor: DFT and docking scrutiny

“…25 2.2. (4). Chalcone (3) (1.0 g, 3.03 mmol) was dissolved in 20 mL DMF by swirling the mixture constantly on the magnetic stirrer.…”

“…The emphasis on analytical cation detection is due to their well-documented pervasive toxic effects on both the terrestrial as well as aquatic living systems, 1-3 thereby rendering their qualitative as well as quantitative recognition as the need of the hour. 4 Due to the unregulated use of lead via mining, smelting, ceramics, paint, automobile exhaust emissions, etc., its accumulation in the environment has undergone an exponential ascent since the latter years of the 'bygone century'. 5 Also, exposure to lead can denature DNA and proteins, is detrimental to bone health, and may result in cell transformation, thereby rendering the cells to become malignant.…”

Selective and Accurate Detection of Nitrate in Aquaculture Water with Surface-Enhanced Raman Scattering (SERS) Using Gold Nanoparticles Decorated with β-Cyclodextrins

“…In the field of water quality monitoring, SERS is currently employed for the detection of various pollutants in water, such as heavy metal ions [ 26 , 27 ], organic compounds [ 28 , 29 ], and microorganisms [ 30 ], providing the rapid monitoring of water pollution. The detection of nitrate nitrogen in water using Raman spectroscopy techniques, especially the application of SERS, has been reported.…”

5-Aminoisophthalate-based kojic acid-appended bis-1,2,3-triazole: a fluorescent chemosensor for Cu2+ sensing and in silico study

“…13,14 The focus on metal cation detection arises from their extensively documented harmful effects on terrestrial and aquatic ecosystems, 15,16 making their qualitative and quantitative identication imperative. 17 As the third-most-common heavy metal ion in the human body, bivalent copper (Cu 2+ ) is an essential ion that plays several roles in biological processes. Functioning as a catalytic cofactor for metalloenzymes, 18 it plays a pivotal role in many critical physiological functions.…”
