Article Synopsis
- Nitrogen and sulfur codoped carbon dots (NSCDs) were created using a simple one-pot hydrothermal process with materials like citric acid and ethylenediamine, resulting in small, spherical particles averaging 1.86 nm in size.
- The NSCDs showed blue fluorescence at 440 nm when excited at 350 nm, with a high quantum yield of 68.0%, making them effective as fluorescent sensors.
- They demonstrated high sensitivity for detecting mercury (Hg) and hypochlorite (ClO) ions, exhibiting significant fluorescence quenching with limits of detection of 0.54 μM for Hg and 0.29 μM for ClO, successfully tested in spiked tap
A simple approach to fabricate a highly selective and sensitive dimethoate probe was developed based on Rhodamine B (RB)-functionalized gold nanoparticles (AuNPs). The quenching of RB fluorescence in the presence of AuNPs in the solution, mediated by fluorescence resonance energy transfer, was observed. In the presence of dimethoate, the fluorescence intensity of the RB-AuNP solution is gradually recovered when dimethoate molecules displace RB molecules on the surface of the AuNPs, which significantly increased the fluorescence intensity of RB.
