Highly improved performance of a film-based fluorescent sensor via a nanomesh scaffold strategy†
Public safety and environmental monitoring are of great significance to maintain human health. Therefore, a simple and effective strategy for preparing the substrate layer of a film-based fluorescent sensor is developed by a nanomesh scaffold technology. The limit of detection of the nanomesh scaffold-modified sensor ranges from 4.8 ppb to 3750 ppm. This can provide an effective method for detecting potential biological warfare agent, 2,6-dicarboxyridine.
