Portable fluorescence sensing platform with 5% Eu-doped g-C3N4 for visual analysis of four tetracycline antibiotics.
Elevated levels of tetracycline antibiotics (TCs) in animal-derived foods threaten human health, necessitating effective residue monitoring. Herein, Eu-doped g-C3N4 fluorescence probe was prepared via high-temperature solid-phase method. Upon interaction with four TCs, g-C3N4's blue fluorescence was quenched by inner f...
