A bifunctional and multi-responsive fluorescent sensor for toxic analytes in the aqueous medium: Easy synthesis, NIR-visible effect, imaging in living cells

An ESIPT solvatochromic fluorescent and colorimetric probe for sensitive and selective detection of copper ions in environmental samples and cell lines

“…The fluorescent properties of some probes have been largely utilized for the visualization of living cells. [39][40][41][42] The ability of QHS to detect Cu(II) in cells was examined in rat glioma cell lines C6 (ATCC, Rockville, USA). Upon performing the cell viability assay, it has been observed that copper chloride inhibited 50% of cells at the concentration of 40 µM at 6 hours and the same effect has been retained for up to 24 hours.…”

Novel Perylene-Based Antimicrobial PDI Chromophores

“…(2) 1 Relative absorption of Compound 1 ''N,N'-O-tbutyl-L-serine t-butyl ester-3,4:9,10-perylene diimide'' and Compound 2 ''N,N'-O-t-butyl-Lthreonine t-butyl ester-3,4:9,10-perylene diimide'' was measured using by UV-Vis spectrometer as these articles (25)(26)(27)…”

A novel fluorescent chemosensor enables dual-channel selective “turn-on” detection of Hg2+ and Ag+via distinct thiophilic effects, essential mechanisms, and excellent sensing performance for mercury(ii) in aggregated states

“…5–8 Compared with traditional detection methods, fluorescence techniques have been widely explored ascribed to their simple operation, cheaper cost, and excellent selectivity and sensitivity. 9–12 Accordingly, various fluorescent sensors for Hg 2+ or Ag + ions have been successfully constructed by using biomacromolecules, luminescent nanoparticles, polymers and small molecules as receptors. 13–17…”
