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 …

Nitrite ions (NO2−), as one of the important inorganic anions, exhibit considerable effects
towards the environment and human health. Moreover, over intake of this anion may cause …

Excessive uptake of NO2− is detrimental to human health, but the currently available
methods used to sensitively detect this ion in the environment are cumbersome and …

Nitrite is a commonly used food additive and water contaminant that has received
widespread attention due to its harmful effects on humans. Here, a colorimetric ratio sensing …

Here, a sensitive and selective strategy for the detection of nitrite via colorimetry and test
strips was developed based on Fe-single-atom catalysts (Fe SACs) through the oxidation …

Abstract Excess nitrite (NO2-) concentrations in water supplies is considered detrimental to
the environment and human health, and is associated with incidence of stomach cancer. In …

Abstract Enzyme-mimicking (nanozyme)-based biosensors are attractive owing to their
unique catalytic efficiency, multifunctionality, and tunable activity, but examples of oxidase …

A colorimetric sensor for nitrite ion with high selectivity and sensitivity by unmodified citrate-
capped gold nanoparticles (Au NPs) is presented. Recognition of nitrite is developed on the …

The research progress on the selective and sensitive fluorescent detection of nitrite anions
has greatly relied on the development of new fluorescent materials. Herein, a novel …

A sensitive and selective colorimetric method for determination of nitrite ion in aqueous
samples was developed using 1-(2-mercaptoethyl)-1, 3, 5-triazinane-2, 4, 6-trione …
