Polyaza functionalized graphene oxide nanomaterial based sensor for Escherichia coli detection in water matrices

Abstract Water quality is widely discussed owing to its significance in public health due to the inability to access clean water. Waterborne diseases account for the presence of pathogens like Escherichia coli (E. coli) in drinking water in the environmental community. Owing to the rapid increase of...
