Interpenetrating polymer network hydrogel bead comprising polyethylene glycol and polyacrylamide, and method for immobilizing enzymes by using the same

摘要

The invention and enzyme immobilization using the same hydrogel beads of polyethylene glycol and polyacrylamide containing interpenetrating structure relates to a process, more particularly formed by a polyethylene glycol (PEG) polyacrylamide hydrogel to the dense structure of the interpenetrating type than by the addition of (PAAm) (IPN), while retaining the benefits of the PEG hydrogel, the mechanical strength is improved and the enzyme chemically to provide functional groups capable of covalently linked enzyme is polyethylene glycol, and the hydrogel beads of the enzyme and the fixing method using the same of the polyacrylamide-containing interpenetrating structure that permanently secured to the hydrogel will.
