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 ...

Enzyme-regulated unmodified gold nanoparticle aggregation: a label free colorimetric assay for rapid and sensitive detection of adenosine deaminase activity and inhibition.

Based on enzyme-regulated unmodified gold nanoparticle aggregation, a visual and homogeneous assay of adenosine deaminase (ADA) activity without any other coupling enzymes, aptamers or additional modifications has been developed. The present strategy is simple, cost-effective, high throughput, selective and sensitive for ADA with a detection limit of 0.8227 U L(-1).

Enhanced DNA sensing via catalytic aggregation of gold nanoparticles.

A catalytic colorimetric detection scheme that incorporates a DNA-based hybridization chain reaction into gold nanoparticles was designed and tested. While direct aggregation forms an inter-particle linkage from only one target DNA strand, catalytic aggregation forms multiple linkages from a single target DNA strand. Gold nanoparticles were functionalized with thiol-modified DNA strands capable...
