We report the development of a novel colorimetric nitrite and nitrate ion assay based upon
gold nanoparticle probes functionalized with Griess reaction reagents. This assay takes …

A novel colorimetric nitrite ion sensor was developed utilizing 4-aminothiophenol (4-ATP)
modified gold nanorods (GNR). In the presence of nitrite ions, the deamination reaction was …

We have developed a simple method for the selective colorimetric detection of aqueous
mercuric (Hg2+), silver (Ag+), and lead (Pb2+) ions by using label-free gold nanoparticles …

Gold nanoparticles (AuNPs) are useful nanomaterials as transducers for colorimetric
sensors because of their high extinction coefficient and ability to change color depending on …

We report colorimetric, label-free, and non-aggregation-based gold nanoparticle (AuNP)
probes for the highly selective detection of Fe (III) ions in aqueous environments. This …

In this work, a novel electrochemical method for nitrite detection by using functionalized
platinum nanoparticles (PtNPs) is proposed. Firstly, a gold electrode is immobilized with 4-(2 …

Colorimetric detection is a simple, fast, and efficient method for determining targets with the
aid of obvious color change.[1] Since no equipment is needed except for the naked eye, it …

We developed two simple, rapid, and cost-effective fluorescent nanosensors, both featuring
bovine serum albumin labeled with fluorescein isothiocyanate (FITC))-capped gold …

Abstract The International Agency for Research cancer (IARC) has classified nitrite in Group
2A of probable carcinogens to human. Herein, we report on the rapid and selective …

The development of rapid, specific, cost‐effective, and robust tools in monitoring Hg2+ levels
in both environmental and biological samples is of utmost importance due to the severe …
