Development of novel carbon black-based heterogeneous oligonucleotide-antibody assay for sulfur mustard detection

Herein, a novel configuration for the detection of a chemical warfare agent, namely sulfur mustard (bis(2-chloroethyl)sulphide) was designed to develop a biosensor that can play a relevant role in the monitoring of such a chemical threat in risk and war areas. In detail, a tailor-made heterogeneous oligonucleotide-antibody biosensor was realised, based on the formation of a sulfur mustard-oligonucleotide adduct on the surface of a screen-printed...
