  • The accurate determination of bisphosphonate levels in bone and biological fluids is important in both clinical and pharmacological/toxicological studies; however, the quantitative analysis of the bisphosphonate is difficult because its concentration is quite low in most of biological sample. A novel fluorescent chemosensor (FCS)-based measurement method of bisphosphaonate levels using Naphta-diDPA-$2Zn^{2+}$ (NadDPA-$2Zn^{2+}$, DPA = dipycolylamine), an excellent FCS previously used for detecting PPi, was developed. By the FCS method, the concentration of bisphosphonates having no fluorophores can be determined analyzed with sufficient sensitivity. The results of this study indicate that the FCS-based measurement can be a useful method to analyze bisphosphonates in biological samples.

  • A new assembly derived from 2,3-dibromo-5,6,7,8-tetrafluoroquinizarin and sodium diethyl-carbamodithiolate, was prepared as an efficient $Fe^{3+}$ colorimetric chemosensor with high selectivity over other cations $Fe^{3+}$, $Na^+$, $Mg^{2+}$, $Pb^{2+}$, $Cd^{2+}$, $Ni^{2+}$, $Ca^{2+}$, $Cu^{2+}$, $Hg^{2+}$, $Zn^{2+}$ : from the dark blue to brown color change that is visible by eyes. This assembly produced large bathochromic shift of 228 nm in the presence of $Fe^{3+}$ compared with the corresponding absorption maximum of the parent dye.
