چکیده
A dinitrophenol-based colorimetric chemosensor sequentially sensing Cu2+ and S2?, HDHT ((E)-2-(2-(2-hydroxy-3,5-dinitrobenzylidene)hydrazineyl)-N,N,N-trimethyl-2-oxoethan-1-aminium), was designed synthesized. The selectively detected through a color change of yellow to colorless. calculated detection limit the for 6.4 × 10?2 ?M. In interference test, not considerably inhibited by various metal ions in its Cu2+. chelation ratio determined as 1:1 using Job plot ESI-MS experiment. addition, HDHT–Cu2+ complex showed that returned only presence S2?. S2? be 1.2 10?1 inhibition experiment did significantly interfere with other anions. real water-sample performance successfully examined. features were suggested plot, UV–Vis, ESI-MS, FT-IR spectroscopy, DFT calculations.

A colorimetric chemosensor for Cu2+ ion detection based on an iridium(III) complex
We report herein the synthesis and application of a series of novel cyclometalated iridium(III) complexes 1-3 bearing a rhodamine-linked NˆN ligand for the detection of Cu(2+) ions. Under the optimised conditions, the complexes exhibited high sensitivity and selectivity for Cu(2+) ions over a panel of other metal ions, and showed consistent performance in a pH value range of 6 to 8. Furthermore...
متن کاملColorimetric Cu2+ detection with a ligation DNAzyme and nanoparticles.
Using a Cu(2+)-dependent DNA ligation DNAzyme, a colorimetric sensor for Cu2+ has been developed based on directed assembly of DNA-functionalized gold nanoparticles by the ligation product, and such ligation DNAzyme-based sensors are intrinsically more sensitive than cleavage DNAzyme systems due to the lack of background.
متن کاملA Low-Cost Video-Based Reflectometer for Selective Detection of Cu2+ Using Paper-Based Colorimetric Sensors
This paper presents a low-cost reflectometer for selective detection of Cu. The reflectometer is based on an emission light source using five light-emitting diodes at different wavelengths and a detector using a webcam. The samples were prepared using a filter paper-based colorimetric sensor with ascorbic acid-based quinoxaline derivative. Video analysis using gray color intensity was used to p...
متن کاملA gold nanorod based colorimetric probe for the rapid and selective detection of Cu2+ ions.
A gold nanorod (AuNR) based colorimetric probe was reported for the rapid and selective detection of Cu(2+) ions. The probe was fabricated by functionalizing cysteine (Cys) onto AuNR (Cys-AuNR) with an aspect ratio of 2.3. The strong coordination of Cu(2+) with cysteine resulted in a stable Cys-Cu-Cys complex, and induced the aggregation of the colloidal nanorods along with a rapid colour chang...
متن کاملHemoglobin detection using curcumin nanoparticles as a colorimetric chemosensor
This article presents a simple and efficient measurement system for quantitative sensing of blood hemoglobin (Hgb) using curcumin nanoparticles (CURNs). The Hgb monitoring is based on CURNs aggregation in the presence of Hgb, which leads to a decrease in the absorption intensity of CURNs. In this study the analytical signal for the measurement of blood Hgb concentration was defined as the diffe...
