A series of amylose-based star polymers (1, 2, 4, and 8 arms) as a new glyco biomaterial was synthesized by a click reaction and enzymatic polymerization of specific primers with phosphorylase. The molecular weights were controlled by the enzymatic reaction. Further polymerization resulted in a viscous solution and, especially, for the 8-arm primer, a hydrogel was obtained due to effective cross-linking between the multiarmed structures. The star polymers with a degree of polymerization of about 60 per arm acted as an allosteric multivalent host for hydrophobic molecules by helical formation. A cationic 8-arm star polymer catalyzed DNA strand exchange as a nucleic acid chaperone. Amylose-based star polymers are promising building blocks for producing advanced hybrid glyco biomaterials.
