A fluorescent probe strategy for the detection and discrimination of hydrogen peroxide and peroxynitrite in cells
Aryl boronate fluorescent probes allow the non-invasive study of dynamic cellular processes involving the reactive species, hydrogen peroxide (H2O2) and peroxynitrite (ONOO−). However, the ability of these probes to differentiate between these two species remains unclear. Here, we report a boronate-...

| সংক্ষিপ্ত: | Aryl boronate fluorescent probes allow the non-invasive study of dynamic cellular processes involving the reactive species, hydrogen peroxide (H2O2) and peroxynitrite (ONOO−). However, the ability of these probes to differentiate between these two species remains unclear. Here, we report a boronate-functionalised hemicyanine dye (<strong>HD-BPin</strong>) as a potential strategy to distinguish between H2O2 at 704 nm (red channel) and ONOO− at 460 nm (blue channel) in solution and in cells. This work also highlights the choice of fluorophore before boronate functionalization can dictate the observed selectivity between these two species. |
