Glyconanogels as a versatile platform for the multivalent presentation of carbohydrates: From monosaccharides to dendritic glycostructures

•Glyconanogels are a platform for the multivalent presentation of carbohydrates.•Nanogels multivalency can be enhanced by introducing glycodendritic structures.•Mannose-containing nanogels interact with the lectin Concanavalin A in solution.•Nanogels prepared from glycodendrons showed an enhanced binding capacity.
