Colorimetric sensing of iodide based on triazole-acetamide functionalized gold nanoparticles

We have modified gold nanoparticles (AuNPs) with triazole acetamide to obtain a material for the sensitive and selective colorimetric determination of iodide. The functionalized AuNPs were prepared by a reductive single chemical step using a Cu(I)-catalyzed click reaction. The presence of iodide ions induces the aggregation of these AuNPs and results in a color change from wine-red to purple. The iodide-induced aggregation can be detected visually with bare eyes, but also by photometry. The detection limit is as low as 15 nM. The method displays excellent selectivity for iodide over other anions due to the selective interaction with the amido groups of the triazole. The method was applied to the determination of iodide in spiked lake waters.

INHIBITION OF IODIDE TRANSPORT IN RAT-THYROID CELLS USING N-SUBSTITUTED ANTHRANILIC ACID-DERIVATIVES

The purpose of this study was to test the effects of chloride channel blockers on iodide uptake in thyroid cells, in the hope of eventually using these blockers to identify and isolate a putative iodide transporter, The chloride channel blockers used in this report are derivatives of N-substituted anthranilic acid and were synthesized using published procedures, For these studies FRTL-5 cells, a line of continuous-growing rat thyroid cells, were used as a model system to study effects on iodide transport. In these cells, there are at least two ways for transmembrane iodide movements, a sodium-dependent influx step and a proposed channel that normally mediates iodide efflux, Two derivatives studied decreased iodide accumulation in FRTL-5 cells, but were found also to lower intracellular pH and ATP levels, To simplify interpretation of the effect of the drugs on iodide transport, we extended the studies using plasma membrane vesicles made from pig thyroid, Iodide entry in these vesicles depended on a sodium gradient and was independent of ATP levels, Iodide transport in plasma membrane vesicles and FRTL-5 cells was measured at 30 sec when the uptake was nearly linear and therefore likely to reflect iodide entry, The uptake was measured using three concentrations of iodide and three of drug. Kinetic analysis of the data described a competitive inhibition by the drugs with a K-i of approximately 250 mu M. In summary, N-substituted anthranilic acid derivatives reversibly inhibit iodide entry in FRTL-5 cells and pig plasma membrane vesicles, Because of their ease of synthesis and modification, these derivatives are potentially useful probes for isolation of the NaI symporter in thyroid.

Thermodynamic analysis of production of high purity titanium by thermal decomposition of titanium iodide

High purity titanium was prepared by thermal decomposition of titanium iodide. The feasible synthetic route and optimum decompositon temperaure were obtained by thermodynamic analysis in the process of thermal decomposition of titanium iodide and nucleation growth theory. The temperature for the formation of titanium iodide is in the range of 800-900 K, at which a large amount of titanium iodide vapour can be obtained. The decomposition temperature of titanium iodide is in the range of 1 300-1 500 K, at which a favourable decomposition rate can be achieved. The experiment results show that the purity of the produced titanium is more than 99.995%.

Samarium(II) iodide mediated transformations of carbohydrate derived alkenyl iodides

D-ribonolactone derived acyclic alkenyl iodides were treated with samarium(II) iodide in THF/MeOH/HMPA at low temperature. Highly functionalized carbocycles are formed if the iodide is tethered to an allylic alcohol, an allylic acetate or an alpha, beta – unsaturated t-butyl ester. The chemoselectivity and diastereoselectively of these transformations vary with the Solvent system and with the reaction temperature. (C) 1997, Elsevier Science Ltd.

Vibration spectroscopic evidence for different interactive modes of iodide on gibbsite in humic acid mediation

Determination of the fate of iodide and associated species is an important scientific question from environmental and nuclear energy perspectives. The chemical kinetics of iodide adsorption on gibbsite was examined in the presence of humic acids (HA). The iodide retention was highest in HA-coated gibbsite (I(I) 15.5 mu mol m(2-); pH 6.50) and lowest in HA-iodide-gibbsite ternary systems (I(I) 9.56 mu mol m(2-); pH 6.50). Both inter- and intralayer OH groups have distinguishable IR manifestations for iodide retention on gibbsite. In HA-coated gibbsite, the enhanced iodide retention was ascribed to direct bonding with surface Al-sites.

Kinetics of iodide uptake and efflux in various human thyroid cancer cells by expressing sodium iodide symporter gene via a recombinant adenovirus

We evaluated the potential of radioiodide therapy in human sodium iodide symporter (hNIS)-defective thyroid cancer cells via exogenous hNIS expression. Three human thyroid cancer cells (ARO, FRO and NPA) of different origin were transduced by a recombinant adenovirus encoding hNIS expression cassette (Rad-hNIS). The cells were efficiently transduced by a recombinant adenovirus in a virus dose-dependent manner. Consequently, the hNIS protein could be readily detected by Western blot analysis 48-h post-infection at 10 infectious virus particles per cell. These hNIS-transduced cells actively transported iodide into the cytoplasm at the level of 11635.3, 61571.6, and 19367.5 pmoles/10(6) cells in ARO, FRO, and NPA, respectively. However, a significant amount of iodide was eluted to an iodide-free media within 60 min in all the cell lines. RT-PCR analysis revealed that the expression of genes related to iodide trapping (Tg, TSHR and TPO) was dramatically downregulated in these cells. The present study indicates that functional hNIS can be efficiently expressed and is responsible for active transport of iodide in hNIS-negative human thyroid cancer cells by a recombinant adenovirus. However, the human thyroid cancer cells, along with down-regulation of iodide metabolism-related gene expression, lose the ability to maintain iodide. Therefore, these kinetic characteristics of iodide uptake and efflux may limit the therapeutic potential of hNIS/radioiodide-based treatment following exogenous hNIS expression in human thyroid cancer.

Highly sensitive determination of iodide by ion chromatography with amperometric detection at a silver-based carbon paste electrode

A silver-based solid carbon paste electrode was developed for use as a detector in ion chromatography (IC) for the sensitive determination of iodide in real samples. Micro- and nano-particles of silver were investigated for the fabrication of different electrodes. The iodide assay was based on IC with amperometric detection (IC-AD) at a silver composite electrode polarized at +0.080 V versus Ag/AgCl. Free iodide and organoiodide compounds were studied. The detection process was characterized by studying the redox behavior of iodide ions at both silver and silver composite electrodes by cyclic voltammetry (CV). The presence of iodide ions in solution was found to considerably facilitate metallic silver oxidation, with response currents directly related to iodide concentration. The calibration curve at the selected silver carbon paste electrode was linear in the concentration range comprised between 0.635 mu g/L and 63.5 mu g/L iodide. The relative standard deviation (R.S.D.) for successive injections was below 3% for all iodide standard solutions investigated. The limit of detection (LOD) was 0.47 mu g/L (3.7 nmol/L) for an injection volume of 20 mu L, i.e. 74 fmol injected. The IC-AD method was successfully applied to the determination of iodide in complex real samples such as table salts, sea products and iodide bound drug compounds. The analytical accuracy was verified by the assay of iodide in milk powder from an iodide certified reference material (CRM) Community Bureau of Reference (BCR) 150. (C) 2008 Elsevier B.V.
