Summary: The study introduces a luminescence method to quantify and detect Staphylococcal enterotoxin A (SEA) using carbon quantum dots as fluorophore, and prepared Fe3O4 nanoparticles loaded with SEA antibody for SEA extraction. By conjugating SEA with Fe3O4@Ab and separating them with a magnet, the fluorescence of CQDs is quenched, providing a fast and reliable method compared with immunoassays. The proposed method showed a linear relationship between SEA concentration and CQDs fluorescent quenching, with a detection limit of 2 pg mL(-1) and good repeatability and reproducibility.

Summary: Human Serum Albumin was utilized as a template and reducing agent to synthesize a label-free fluorescent sensor for detecting Hg2+ and biothiols. The sensor could specifically recognize Hg2+ through aggregation-induced fluorescence quenching, which could be reversed by increasing the concentration of biothiols. The detection limits were determined to be 55 pM for Hg(II) and 14 nM for GSH.
