[ 1 ] - Spectrophotometric Determination of 4-Hydroxy-2-mercapto-6-methylpyrimidine Based on Aggregation of Colloidal Gold Nanoparticles

We report herein the development of a highly sensitive colorimetric method for the detection of 4-hydroxy-2-mercapto-6-methylpyrimidine (MTU) which acts as an anti-thyroid drug utilizing citrate capped gold nanoparticles (Au-NPs). This thiol-containing molecule exhibits intriguing affinity with Au-NPs. The reactivity involves the displacement of the citrate shell by the thiolate shell followed ...
