abstract = {Crosslinking of polyethylene oxide (PEO) using a peroxide
in the melt is employed to synthesize soft hydrogels with
the ability of controlled release of proteins. The
viscoelastic properties of the swollen networks confirm the
elastic nature of the synthesized material and they are in
agreement with swelling characteristics. The hydrogels have
mesh sizes at the nm scale as it is estimated by swelling
measurements and measured by small angle neutron scattering
(SANS). Diffusion of bovine serum albumin (BSA) and lysozyme
(LYZ) out of the hydrogels is restricted by the presence of
the network. The diffusion coefficient in the hydrogels is
lower for BSA in comparison to LYZ, while in both cases it
drops as the mesh size of the network becomes smaller. This
study introduces the use of peroxide-crosslinked PEO
networks in the investigation of protein transport within
hydrogels, the development of hydrogel-based protein
delivery patches and polymeric constructs},
