Article Synopsis
- A fluorescent quinone-capped silver hydrosol (AgOSA) was created using salicylaldehyde and ionic silver, which was then quenched by the toxic Congo red dye (CR), transforming it into CRAgOSA due to strong silver-sulfur interactions.
- The addition of cobalt ions restored fluorescence in the compound (CoCRAgOSA), enhancing it by 8.3 times compared to AgOSA because it freed CR and reduced self-quenching from excess quinone.
- The research developed a sensitive ionic cobalt sensor with high detection capabilities, simultaneously allowing colorimetric sensing of mercury, while also addressing environmental concerns by chemisorbing the toxic CR dye through the nanosensor.
