摘要: The development of a user-friendly sensing platform for the detection Cu2+ in water is necessary as there are wide concerns due to substantial impact on human health, environmental monitoring, and so on. Motivated by this, we report fluorescent silver nanoclusters (AgNCs)-based sensor Cu2+. These water-soluble AgNCs, new class probes, were synthesized using azobenzene modified poly(acrylic acid) (MPAA) templates. Their fluorescence can be quenched presence Cu2+, which enables label-free real samples. Furthermore, such AgNCs integrated onto cellulose filter paper used indicators quenching observed naked eye under UV light. It should noted that this AgNCs-based assay performs successfully barrelled drinking river Therefore, it opens up avenues robust clusters-based platforms.
