Rose Bengal-derived pH-sensitive carbon quantum dots for the detection of urea and urease activity

In this work, rose Bengal-derived carbon quantum dots (S-CQDs) were prepared by a one-step solvothermal method in ethanol using rose Bengal and 2-aminothiophenol as raw materials. The morphological properties, surface functional group information, elemental composition and optical properties of S-CQDs were carefully ch...

A pyrene-based fluorescent probe for highly sensitive and selective detection of hydroxylamine in environmental water samples

In this study, a pyrene-based fluorescent probe (PCPA) was designed, synthesized and developed for the detection of HA. In the presence of HA, PCPA was converted to the oxime derivative (PCO) through a nucleophilic addition–elimination reaction, accompanied by significant enhancement in fluorescence at 408/425 nm. Furt...
