Tumor-associated carbohydrate antigens(TACAs)provide a special class of tumor-specific antigens that show promising applications in cancer immunotherapy.However,the weak immunogenicity and structural complexity of TACAs are obstacles to their clinical application.Here,based on a fast and low-cost purification strategy for oligosaccharide synthesis,the synthesis of tumour-associated carbohydrate antigens Globo H and mannobiose which resembles repeat unit of mannan was achieved.To enhance the immunogenicity and multivalent effect,Globo H and mannobiose were covalently attached to degradable polymer backbones.2D spindle-like lamellar micelle and globular micelle were ob-tained from glycopolymer through a solvent-exchange method of self-assembly.The glyconanoparticle showed good biocompatibility and degradability.Immunological functions of these glyconanoparticles such as stimulation of BMDC to cause upregulation of inflammatory factors were preliminarily explored.
