Cyclodextrin-Modified Gold Nanoparticle Aggregate formed by Simple host–Guest Interactions with 1,10-Phenanthroline

An aggregate of gold nanoparticles modified with thiolated β-cyclodextrin was fabricated through the linkage of PHEN and characterised by FT-IR, UV-vis, fluorescence and STM techniques, showing that the aggregate formation was a concentration-dependant behaviour.
