A chemoenzymatic method for the preparation of a homogeneous glycoprotein or glycopeptide, including (a) providing an acceptor selected from the group consisting of GlcNAc-protein and GlcNAc-peptide; and (b) reacting the acceptor with a donor substrate including an activated oligosaccharide moiety, in the presence of a catalyst comprising endoglycosidase (ENGase), to transfer the oligosaccharide moiety to the acceptor and yield the homogeneous glycoprotein or glycopeptide. The donor substrate includes, in a specific implementation, a synthetic oligosaccharide oxazoline. A related method of glycoprotein or glycopeptide remodeling with a predetermined natural N-glycan or a tailor-made oligosaccharide moiety, and a method of remodeling an antibody including a heterogeneous sugar chain, are also described. The disclosed methodology enables glycoprotein drugs to be modified for prolonged half-life in vivo, reduced immunogenicity, and enhanced in vivo activity, and for targeting and drug delivery.

Hydrophilic polymer particles have been obtained using polyacrylamide, xanthane, maleic anhydride polymers, allylamine, ethyleneimine, and oxazoline as core polymers. Then, hydrophobic polymers shells have been produced on the core-side using styrene, styrene copolymers, polyvinyl state, polysolfune, polymethyl methacrylate, and polycyclohxyl methacrylate by in-situ polymerization of monomer as method one and inverse emulsion process as method two. These particles can release hydrophilic polymers at oil-water interface at the reservoir temperature where the water flooding should have the maximum viscosity. So, active materials cause to decrease the mobility ratio of water to oil in the reservoirs and on the other hand, plug the swept porosities and prevent to act the water fingering process.
