Various techniques for the determination of nitrite and/or nitrate developed during the past
15 years were reviewed in this article. 169 references were covered. The detection …

Nitrate is an important pollutant found in environmental samples. Nitrate and nitrite pose
various environmental as well as health hazards. Different methods of determining nitrate in …

Superior photostability, minimal phototoxicity, red-shifted absorption/emission wavelengths,
high brightness, and an enlarged Stokes shift are essential characteristics of top-tier organic …

Fluorescence imaging is one of the most powerful techniques for monitoring biomolecules in
living systems. Fluorescent sensors with absorption and emission in the near-infrared (NIR) …

Abstract Nitrite (NO 2–) is a common chemical substance that widely exists in nature and
human life, such as in food, drinking water, soil, etc. Excessive intake of NO 2–will lead to …

A new hemicyanine-based near-infrared" off-on" recognition Cu 2+ fluorescent probe NRh-
NP was designed and successfully synthesized. The structure of NRh-NP was characterized …

Nitrite is an important food additive for cured meats; however, high nitrite levels pose
adverse health effects to humans. Hence, monitoring nitrite concentration is critical to comply …

In this work, a simple and effective strategy for designing a ratiometric fluorescent
nanosensor was described. A carbon dots (CDs) based dual-emission nanosensor for nitrite …

Nitrites are the upstream precursors of the carcinogenic nitrosamines, which are widely
found in the natural environment and many food products. It is important to develop a simple …

Near-infrared fluorescent gold nanoclusters (AuNCs) were prepared by sonochemical
method and applied for the selective and sensitive detection of nitrite. The fluorescence of …
