WebFluorescence-based detection techniques are popular in high throughput screening due to sensitivity and cost-effectiveness. Four commonly used techniques exist, each with distinct characteristics. Fluorescence intensity assays are the simplest to run, but suffer the most from signal interference. WebJul 4, 2024 · As shown in Fig. 3b, the subsequent addition of H 2 O 2 rapidly led to an increase in fluorescence intensity. TCBT-OMe was shown to be selective towards Hg 2+ over other metal cations in the presence of H 2 O 2 (see ESI,† Fig. S9). Interestingly, Hg 2+ alone resulted in a slow increase in fluorescence intensity (see ESI,† Fig. S10). rdxsidewarninglight
