“…Vellingiri et al 49 demonstrated the identification of nitrite ions (NO 2 − ) in water and wastewater by employing fuchsin dye as a colorimetric indicator. They applied basic fuchsin (BF) onto Whatman filter paper, and observed that when NO 2 − ions at various concentrations ranging from 0.005 to 9.2 mg L −1 were introduced to the BF-coated paper, a noticeable color transition from pink to colorless ensued as a result of diazotization.…”

Nitrite (NO2‐) is an anionic species that holds paramount significance in cellular signalling pathways and have crucial physiological functions. Nevertheless, an excessive accumulation of nitrite ions can induce detrimental effects, including intrauterine growth restriction, birth abnormalities, and methemoglobinemia. Thus, quantitative detection of nitrite ions for in vivo and invitro studies is very important. This review presents a comprehensive overview of colorimetric techniques employed for the detection of nitrite ions. Various methodologies have been developed, encompassing diazo reaction‐based sensing, nitrosation reaction‐based sensing, redox reaction‐based sensing, non‐covalent interaction‐based sensing, and other approaches. Each method will be systematically discussed and critically evaluated in the context of this review.

“…There are only limited reports about the development of a ratiometric fluorescent test paper detecting NO 2 − . 33 Rhodamine B (RhB) is a kind of fluorescent dye that can emit dazzling fluorescent color under the ultraviolet light. It has the characteristics of good photostability at a very low cost.…”
