In an article, author is Du, Fangkai, once mentioned the application of 3058-39-7, Safety of 4-Iodobenzonitrile, Name is 4-Iodobenzonitrile, molecular formula is C7H4IN, molecular weight is 229.02, MDL number is MFCD00051310, category is iodides-buliding-blocks. Now introduce a scientific discovery about this category.
Carbon dots-based fluorescent probes for sensitive and selective detection of iodide
We report on a simple method for the determination of iodide in aqueous solution by exploiting the fluorescence enhancement that is observed if the complex formed between carbon dots and mercury ion is exposed to iodide. Fluorescent carbon dots (C-dots) were treated with Hg(II) ion which causes quenching of the emission of the C-dots. On addition of iodide, the Hg(II) ions are removed from the complex due to the strong interaction between Hg(II) and iodide. This causes the fluorescence to be restored and enables iodide to be determined in the 0.5 to 20 mu M concentration range and with a detection limit of similar to 430 nM. The test is highly selective for iodide (over common other anions) and was used for the determination of iodide in urine.
