چکیده
In this study, a mixture of [Zn(2)(1,3-bis[bis(2-pyridylmethyl)aminomethyl]benzene)](4+) ([Zn(2)(BBPAB)](4+)) and 11-mercaptoundecylphosphoric acid functionalized gold nanoparticles (Phos-AuNPs) is shown to be a highly sensitive colorimetric probe that can easily detect pyrophosphate (PPi) at less than 200 nM with the naked eye.

Highly specific colorimetric recognition and sensing of sulfide with glutathione-modified gold nanoparticle probe based on an anion-for-molecule ligand exchange reaction.
Colorimetric recognition and sensing of sulfide with high selectivity by virtue of glutathione-modified gold nanoparticle (GSH-AuNP) is presented. The assay is developed based on a specific anion-for-molecule ligand exchange reaction, through which sulfide replaces glutathione self-assembled on the AuNP. The unique feature of the GSH-AuNP probe makes it a novel colorimetric sensor for sulfide.

متن کاملA highly sensitive gold-nanoparticle-based assay for acetylcholinesterase in cerebrospinal fluid of transgenic mice with Alzheimer's disease.
A highly sensitive, selective, and dual-readout (colorimetric and fluorometric) assay for acetylcholinesterase (AChE) based on Rhodamine B-modified gold nanoparticle is reported. Due to its good sensitivity and selectivity, the assay can be used for monitoring AChE levels in the cerebrospinal fluid of transgenic mice with Alzheimer's disease.
متن کاملAssessing Stability of Gold Nanoparticles in Presence of Two Enzymes, RNaseA and RNaseH, Using Colorimetric Detection
Gold nanoparticle-based diagnostic methods have attracted much attention due to their simplicity, high sensitivity and low cost. These methods are mostly used for early and efficient detection of various pathogenic factors and assessment of gene expression and nanoparticles stability. In this study, melon plants were cultured in vivo and then, RNA was extracted from leaf explants. A 40 bp probe...
متن کاملGold nanoparticle-based exonuclease III signal amplification for highly sensitive colorimetric detection of folate receptor.
By combining terminal protection of small molecule (folate)-capped DNA probes, exonuclease III signal amplification and gold nanoparticles, we developed a simple and label-free colorimetric assay for highly sensitive detection of folate receptor (FR). A detection limit of 50 fM FR was obtained using UV-vis spectrometry and 10 pM FR could be visualized by the naked eye.
