A novel water insoluble, multifunctional poly(ethylene glycol), poly(hydrazide ethylene glycol-co-benzyl glycidyl ether) (P(HZ-co-BnGE)), is synthesized via thiol-ene click reaction of poly(allyl glycidyl ether-co-benzyl glycidyl ether) (P(AGE-co-BnGE)). The base polymer P(AGE-co-BnGE) is previously prepared by anionic ring-opening copolymerization of the corresponding monomers. To demonstrate utility, bicompartmental microspheres and microcylinders containing P(HZ-co-BnGE) in one of the compartments are prepared via electrohydrodynamic (EHD) co-jetting.

Next, spatially controlled surface reactivity toward sugars is demonstrated by selective binding of 2α-mannobiose to the P(HZ-co-BnGE) compartment only, as confirmed by a carbohydrate-lectin-binding assay. These sugar-reactive hydrazide-presenting microparticles have potential applications for glyco-targeted drug delivery.
