l-cysteine double layer protected gold nanoclusters (Au NCs) have projected thiol groups that induce hydrophobicity around the NCs attracting the relatively hydrophobic cavities of cyclodextrins (CDs) to accumulate around. The different sizes of the CDs result into different accumulating patterns to form spherical to cuboid aggregates with embedded Au NCs.
