Figure 1: Chemical structure and construction of PEI-Ada-PBCD Supramolecular Nanocluster.
From: Simultaneous expression and transportation of insulin by supramolecular polysaccharide nanocluster

Nanocluster was constructed by host-guest inclusion of adamantane with β-CD and further crosslinking between boronic acid with PEI-Ada, and could be used for insulin and pCMV-Ins plasmid co-delivery.
