Synthesis,Emission and Intracellular Temperature Sensing of Cu Nanoclusters Assembly
Emissive metal nanoclusters have received considerable research attention owing to their low toxicity,low cost,and good biocompatibility,but the preparation of Cu nanoclusters assemblies with strong emission behavior is a large challenge.Chiral ligand D-penicillamine was used as a reactant to construct intense emission of luminescent Cu nanoclusters assembly by"one-pot"method.They have been characterized by multiple techniques including FT-IR specta,thermogravimetric analysis,X-ray photoelectron spectra,X-ray diffraction pattern,scanning electron microscopy(SEM),transmission e-lectron microscopy(TEM),photoluminescence spectra,and cellular imaging.The results show that Cu nanoclusters assemblies in suspension solution and solid state show very strong emission with the abso-lute photoluminescence quantum yield as high as 30.4%.Moreover,emissive Cu nanoclusters assem-blies possess very low cellular toxicity and can be used as cellular imaging as well as the temperature-dependent intracellular imaging agent in HepG2 cells.The application exploration on cellular imaging of Cu nanoclusters assembly with strong emission behavior provides significant references for their ap-plications in other areas.
