Synthesis of Fluorescent Hollow Silica Nanoparticles and Application in Detecting Hypochlorite

Abstract In this paper, fluorescent hollow silica nanoparticles (FHSNs) have been used for the detection of hypochlorite by monitoring fluorescence intensity changes. The fluorescent and sensing properties of the FHSNs were dramatically improved compared to those of the corresponding free probes. With unique hollow structure and strong fluorescence, the FHSNs have potential applications in the fields of biology and medicine.
