Abstract
- Quinoline-appended rhodamine B thiohydrazide based fluorescent probe was designed and applied in fluorescent detections of mercury ions in both aqueous solution and living cells. The signal change of the probe is based on a specific metal ion induced reversible ring-opening mechanism of a rhodamine B thiohydrazide. The probe exhibits a dynamic response concentration range for Hg2+ from 1.0 × 10-8 to 1.0 × 10-5 M with a detection limit of 8.5 × 10-9 M. The fluorescent probe is pH independent in medium condition and exhibits high selectivity over other common metal ions. [ABSTRACT FROM AUTHOR]
