A FRET system was built for ratiometric sensing of Hg(2+) in water with multilayered silica nanoparticles as the scaffold. This architecture ensures the control over the location of both donor and acceptor and their separation distance within nanoparticles, affording higher energy transfer efficiency and higher signal-to-background ratio for particle-based sensing.
构建了一种荧光能量共振转移(FRET)体系，用于在水介质中对 Hg(2+)进行比率型检测，其中多层二氧化硅纳米粒子作为载体。该结构确保了供体和受体的位置以及它们在纳米粒子内的分离距离都得到了有效控制，从而提高了基于粒子的传感中的能量转移效率和信号背景比。
