Detection with NO Modification: (N═O)-Au Interactions for Instantaneous Label-Free Detection of -Nitrosodiphenylamine.

Increasing concerns have been raised about dangerous, yet nearly undetectable levels of nitrosamines in foods, medications, and drinking water. Their ubiquitous presence and carcinogenicity necessitates a method of sensitive and selective detection of these potent toxins. While the detection of two major nitrosamines─-nitrosodimethylamine and -nitrosodiethylamine─has seen success, low detection limits are scarcer for the other members of this class.
