WebThe greatest advantage of activatable fluorescence probes (AFPs) is the inherent responsiveness to manipulate spectroscopic properties by chemical/physical interactions with the biological analytes/microenvironmental factors. As alternatives to “always-on” fluorescence probes, AFPs in the first near-infrared (NIR-I) window expanded … Web30 de abr. de 2024 · For “on-off” fluorescent switches, the most common is the binary combination composed by GQDs and metal cations. Many studies have shown that the fluorescence of GQDs can be quenched by metal cation, leading to the formation of “on-off” switch that can be used for the ion detection [19] , [20] , [21] .
