Abstract: Herein, we present the development and evaluation of a molecularly imprinted polymer (MIP) sensor for the sensitive and selective detection of N-nitrosodimethylamine (NDMA) in aqueous environments. MIP coatings over electrochemically active electrodes enable NDMA detection with a notably low detection limit of 1.16 ppb. Our findings demonstrate that the ...

Agglutination of liquid Janus emulsions creates optical signals that can be detected and quantified. This study reports the detection and quantitation of Interleukin-6 (IL-6) using emulsions functionalized at the water-organic interface with engineered hyperthermophilic affinity proteins (rcSso7d) derived from ...

The comet assay is a versatile assay for detecting DNA damage in eukaryotic cells. The assay can measure the levels of various types of damage, including DNA strand breaks, abasic sites and alkali-sensitive sites. Furthermore, the assay can also be modified to include purified DNA glycosylases so that alkylated and oxidized bases can be detected. The ...

Cu(I) from tetrakis(acetonitrile)copper(I) hexafluorophosphate ([Cu(MeCN)4]PF6) was complexed with five structurally related phosphines containing N-heterocycles. The interactions between the resulting complexes and some N-nitrosamines were studied using X-ray crystallography as well as emission spectroscopy. Upon complexation, three ...
