Study of graphdiyne biomimetic nanomaterials as fluorescent sensors of ciprofloxacin hydrochloride in water environment

Ciprofloxacin hydrochloride is widely used in aquaculture industry, and is often used as fishery medicine to prevent and treat bacterial infection diseases in aquatic animals. However, the drug will enter the environment in the form of primitive form or metabolites, directly threatening public health safety and polluting the ecological environment. In this study, based on graphdiyne quantum dot (GDYQDs), a new nanocomplex dopamine-graphdiyne quantum dot (DA-GDYQDs) was prepared using the mussel bionic nanotechnology. And DA-GDYQDs was used to build a fluorescence sensing system for quantitative detection of ciprofloxacin hydrochloride. The experimental results proved that DA-GDYQDs can be used in detecting ciprofloxacin residue in water quickly and effectively.
