文摘

Two site-specific nanocomposite samples were reported for nitrite sensing. These two composite samples and their core-shell structure were investigated. Nitrite sensing performance was evaluated with their emission quenching. A static sensing mechanism was observed with LOD of 1.1 μM and recyclability.
