Fig. 1. (a) Structure of the fluorophore-labeled glycoligands (HXLs) with adamantane as a cyclodextrin binder and cartoon of HXL2, SH-cyclodextrin (SH-CD) and gold nanoparticle (AuNP). (b) Schematic illustration of the nanocomposite based on the host–guest interaction between CD-AuNP and HXL2 with quenched fluorescence, and enhancement of both fluorescence and reactive oxygen (ROS) production by ligand–receptor recognition.
