the present invention relates to a polymerizable macromers for applications in medicine and biotechnology and synthesis thereof . macromers comprises polyvalent various carbohydrates including n - acetyl glucosamine which bind more efficiently to lysozyme than nag itself . effective inhibition of lysozyme is possible even at very low ligand concentrations . the polymerizable macromer could be used for prevention and treatment of bacterial and viral infections . moreover these macromers can be copolymerized with other comonomers to form stimuli sensitive polymers and used for the recovery of biomolecules . the methodology can be extended to other ligands such as sialic acid and used for preventing influenza and / or rotavirus infections .
