WebShabnam Sharifzadeh, ... Erin E. Carlson, in Methods in Enzymology, 2024 5.1 Probe concentration. Fluorescent probe concentrations were determined by measuring UV-Vis absorption of each solution at λ max of its corresponding fluorophore. Probes were stored as DMSO solutions at −80 °C.For 7FL probe, 10× and 100× dilutions of the probe were … WebGraphene quantum dots (GQDs) have been widely used as fluorescence probes to detect metal ions with satisfactory selectivity. However, the diverse chemical structures of GQDs lead to selectivity for multiple metal ions, and this can lead to trouble in the interpretation of selectivity due to the lack of an in depth and systematic analysis. Herein, bare GQDs …
