FieldPortable Nitrate/Nitrite Sensor |

Nitrate contamination of drinking water is a major worldwide health threat and is responsible for many human and livestock illness. Excessive nitrates/nitrites in drinking water and the associated human health problems has prompted the EPA to set the maximum nitrate level in drinking water at 10mg/L (10 ppm) [1 mg/L for nitrites].

RapidResponse and Highly Sensitive NoncrossLinking ...

Apr 07, 2010· A novel colorimetric nitrite ion sensor was developed utilizing 4aminothiophenol (4ATP) modified gold nanorods (GNR). In the presence of nitrite ions, the deamination reaction was induced by heating the 4ATP modified GNR in ethanol solution, resulting in the reduction of the GNR surface charges, which led to aggregation of GNRs and a colorimetric response that was quantitatively …

narX Nitrate/nitrite sensor protein NarX Escherichia ...

Dec 20, 2005· Acts as a sensor for nitrate/nitrite and transduces signal of nitrate availability to the NarL protein and of both nitrate/nitrite to the NarP protein. NarX probably activates NarL and NarP by phosphorylation in the presence of nitrate. NarX also plays a negative role in controlling NarL activity, probably through dephosphorylation in the absence of nitrate.
