Highly sensitive and selective colorimetric detection of iodide based on anti-aggregation of gold nanoparticles

A simple and reliable colorimetric detection method for iodide has been well established based on the antiaggregation effect of AuNPs in this paper. This assay is highly sensitive and selective toward iodide over other interferent anions due to the high stability of the inorganic complex formed between Hg2+ and iodide. In the absence of iodide, T-rich single-stranded DNA (ssDNA) can specifically bind with Hg2+ to form a stable T-Hg2+-T complex, inducing the solution color change from wine-red to finally violet blue with increasing concentration of Hg2+. However, when Hg2+ is first treated with iodide, the T-Hg2+-T interaction will be interrupted, which results in the anti-aggregation of AuNPs. A linear response from 4 x 10(-8) to 4 x 10(-6) M was obtained for iodide, and a detection limit of 13 nM was achieved.

Selective Detection of Iodine/Iodide Using BSA-stabilized Gold Nanoclusters-based Fluorescence Probe

In the present study BSA (bovine serum albumin)-stabilized Au nanoclusters (AuNCs@BSA) were demonstrated as a novel fluorescence probe for sensitive and selective detection of iodine/iodide. Beyond that, the proposed method was successfully applied to the determination of iodine in kelp, meanwhile, after iodide was changed to iodine with redox reactions, the detection of iodide could be successfully achieved using the AuNCs@BSA. This method could be used as a reliable, rapid, and cost-effective technique for the determination of iodine/iodide in real samples.

Laccase-Catalyzed Oxidation of Iodide and Formation of Organically Bound Iodine in Soils

Laccase oxidizes iodide to molecular iodine or hypoiodous acid, both of which are easily incorporated into natural soil organic matter. In this study, iodide sorption and laccase activity in 2 types of Japanese soil were determined under various experimental conditions to evaluate possible involvement of this enzyme in the sorption of iodide. Batch sorption experiment using radioactive iodide tracer (I-125(-)) revealed that the sorption was significantly inhibited by autoclaving (121 degrees C, 40 min), heat treatment (80 and 100 degrees C, 10 min), gamma-irradiation (30 kGy), N-2 gas flushing, and addition of reducing agents and general laccase inhibitors (KCN and NaN3). Interestingly, very similar tendency of inhibition was observed in soil laccase activity, which was determined using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) as a substrate. The partition coefficient (K-d: mL g(-1)) for iodide and specific activity of laccase in soils (Unit g(-1)) showed significant positive correlation in both soil samples. Addition of a bacterial laccase with an iodide-oxidizing activity to the soils strongly enhanced the sorption of iodide. Furthermore, the enzyme addition partially restored iodide sorption capacity of the autoclaved soil samples. These results suggest that microbial laccase is involved in iodide sorption on soils through the oxidation of iodide.

The determination of iodide based on a flow-injection coupling irreversible biamperometry

A novel flow-injection irreversible biamperometric method is described for the direct determination of iodide. The method is based on electrochemical oxidation of iodide at the gold electrode and the reduction of permanganate at the platinum electrode to form an irreversible biamperometric detection system. Under the applied potential difference of 0 V, in the 0.05 mol/L sulfuric acid, iodide can be determined over the range 4.00×10(-7)-1.00×10(-5) mol/L with a sampling frequency of 120 samples per hour. The detection limit for I is 3.0×10(-7) mol/L and the RSD for 40 replicate determinations of 4.0×10(-5) mol/L potassium iodide is 1.68%. The new method was applied to the analysis of iodide in table salt with satisfactory results.

Effect of soil physical factors on methyl iodide and methyl bromide

Production and importation of methyl bromide is scheduled to be banned by 2001. Methyl iodide was evaluated as a possible replacement soil fumigant. The effects of soil moisture, temperature, soil texture and fumigation time on the efficacy of methyl iodide for the control of two common weeds, Abutilon theophrasti and Lolium multiflorum, were characterized and compared with those of methyl bromide. The optimal soil moisture for methyl iodide to kill both weed species in sandy soils was 14% water content (w/w). Greater efficacy was obtained when the temperature during fumigation was above 20 degrees C. Compared to methyl bromide, the efficacy of methyl iodide was more consistent in different soils. Time to 100% mortality of weeds was 24 h for methyl iodide fumigation and 36 h for methyl bromide when 200 mu M of fumigant was used. On a molar basis methyl iodide was consistently more effective than methyl bromide across the range of environmental factors tested. In terms of application technology and spectrum of activity, methyl bromide can be directly replaced by methyl iodide. (C) 1998 SCI.

Effects of iodide on thyroglobulin biosynthesis in FRTL-5 cells

Iodide inhibits several thyroid parameters through an organic intermediate, and this process has been related to thyroid autoregulation. The aim of this study was to determine the effect of iodine on thyroglobulin (Tg) synthesis in the rat thyroid cell line FRTL-5. TSH stimulated amino acid incorporation into the cells by 400% and iodine had no effect on this parameter. No effect of TSH or iodide on [S-35]methionine incorporation into protein was found under our experimental conditions (similar to 80% of total [S-35]methionine incorporated was found in TCA-precipitable material). TSH caused an increase in Tg synthesis, after 1 h, while iodide partially blocked the effect of TSH (controls 6.4% of TCA precipitable radioactivity; TSH 10.7%; iodide 8.4%). After 24 h, the protein released into the medium was measured. TSH stimulated total protein liberation and iodide inhibited this parameter. TSH stimulated total RNA content, and iodide caused an inhibition. Northern analysis did not show inhibition by iodide of TSH-stimulated Tg mRNA levels. The present results show an inhibitory effect of excess iodide on TSH-stimulated thyroglobulin biosynthesis in FRTL-5 cells.

Impact of Residual Lead Iodide on Photophysical Properties of Lead Triiodide Perovskite Solar Cells

The role of residual lead iodide on the photophysical properties of methylammonium lead iodide is still unclear and contradictory views exist about its impact. Herein, it is reported that there is a critical amount of residual lead iodide, which is beneficial for the solar cell performance. Transient absorption spectroscopy is used to investigate the charge carrier recombination dynamics in perovskite solar cells and to address the role of different amounts of residual lead iodide. The amount of lead iodide is varied through the perovskite thin film preparation protocol upon a modified two-step fabrication process. Slower carrier dynamics are observed at the perovskite/titanium dioxide interface in the presence of residual lead iodide when exciting the perovskite at the perovskite/titanium interface, which correlates with improved solar cell device performance. Excitation from the perovskite side indicates that the effect of residual lead iodide is primarily at the titanium dioxide interface. Increasing the lead iodide content does not further alter the carrier recombination; on the contrary, it results in lower device performance. This study confirms that the presence of lead iodide can have a beneficial effect, as it reduces charge carrier recombination at the perovskite/titanium dioxide interface.
