Abnormal glutathione (GSH) levels are directly related to specific diseases. Therefore, the highly sensitive detection of GSH has attracted extensive attention of researchers. Here, we reported a novel electrochemiluminescence (ECL) biosensor platform based on AgGaS quantum dots (AGS QDs) for sensitive detection of GSH released by living cancer cells.

Here, we report Au@ZnO@SiO-ICG nanomotors as an antibacterial candidate. Firstly, we prepared the Janus structure Au@ZnO loaded with indocyanine green (ICG) and constructed a synergistic antibacterial platform with photothermal and photodynamic properties triggered by dual light sources.

At present, research on this material has gradually expanded into the biological field. Herein, the biomineralization method mediated by bovine serum albumin (BSA) was utilized to synthesize BiS QDs with monodispersity, excellent colloidal stability, and good biocompatibility.
