Highly luminescent gold nanocluster assemblies for bioimaging in living organisms
Abstract:
Fluorescent gold nanoclusters are promising nanomaterials for biomedical applications but confronted with low emission efficiency and poor surface functionality. Herein, three kinds of highly luminescent and functionalized gold nanocluster nano-assembled structures were fabricated by poly-l-arginine surface engineering for luminescence improvement. The assembly is employed for imaging the glutathione molecule in cells and living organisms with low background and high sensitivity.
