One-pot synthesis of β-cyclodextrin modified Au nanocluster with near-infrared emission

β-cyclodextrin modified gold nanoclusters (AuNCs@β-CD) with near-infrared (NIR) emission were facilely and successfully prepared based on a one-pot and green synthetic route, which supplies an interesting and efficient strategy to realize NIR emissive nanoclusters via supramolecular macrocycle modification.
