We synthesized sialoglyco-nanoparticles using a spherical nanocluster backbone of sugar units.
Highly-branched α-glucuronic acid-linked cyclic dextrins were used in the backbone.
Particles display high-functionalization, low polydispersity and controlled diameter.
Sialoglyco-nanoparticles exhibited high affinity against human influenza virus hemagglutinin.
