Applications of core?shell nanostructure of FITC-doped silica bead have been changing considerably as advances in core?shell nanostructure of FITC-doped silica bead. Early on, this nanoparticle was mainly used for biological imaging, but nowdays It is studied a lot as a tool of quantitative analysis. Quantitative analysis requires high accuracy. Therefore, it has to be known the effects on fluorescence of core-shell nanoparticle in order to get high accuracy. However, olny a few researches of the effects on fluorescence of core-shell nanoparticle have been studied. In here, we studied the effect of various metal ions on fluorescence of core-shell nanoparticle using FITC doped silica nanoparticle. We used seven metals such as Hg2+, Cd2+, Pb2+ Ca2+, Mg2+, K+ and Na+. For quantitative detection, we use a lab-built laser induced fluorescence microscope (LIFM) with Photomultiplier tube(PMT) and 473nm DPSS Laser(with 500nm~550nm interference filter). As a result, Dication caused more quenching than Monocation and the smaller size of metal is, the more quenching we can observe. Furthermore, we observed this quenching at pH5 and pH9. we used the same kinds of Nanoparticle which was synthesized at 80℃ in order to compare the level of quenching
