Diffusion of small molecular weight drugs in radiation-crosslinked poly(ethylene oxide) hydrogels
Poly(ethylene oxide) (PEO) hydrogels were formed by crosslinking of aqueous PEO solutions of IVI = 35 000, 900 000 and 5 000 000 in concentrations of 5-50% using T-irradiation with 3-10 Mrad. The hydrogels were characterized by equilibrium swelling experiments. The average interjunction molecular weight, 1VI c, varied from 3500 to 32 000, whereas the mesh size, ~:, varied from 120 to 550 ,~. Th...
متن کاملDrug diffusion and binding in ionizable interpenetrating networks from poly(vinyl alcohol) and poly(acrylic acid).
Hydrogels of poly(vinyl alcohol) (PVA), poly(acrylic acid) (PAA), and their interpenetrating networks (IPNs) were prepared using glutaraldehyde and ethylene glycol dimethacrylate as crosslinking agents. The hydrogels were characterized by measuring their equilibrium polymer volume fraction, equilibrium swelling ratio, and mesh size. Drug and protein diffusion through these hydrogels were studie...
متن کاملTransport of ionizable drugs and proteins in crosslinked poly(acrylic acid) and poly(acrylic acid-co-2-hydroxyethyl methacrylate) hydrogels. II. Diffusion and release studies
The goal of this research was to define the controlling parameters affecting transport of drugs and proteins through poly(acrylic acid), PAA, and poly(acrylic acid-co-2-hydroxyethyl methacrylate), P(AA-co-HEMA). The hydrogel formulation variables investigated included the amount of crosslinking agent and non-ionizable comonomer (i.e. HEMA), which ultimately defined the mesh size available for s...
متن کاملDiffusion and interaction in PEG-DA hydrogels.
Polyethylenglycol (PEG) hydrogels are widely used as tuneable substrates for biological and technical applications due to their good biocompatibility and their high hydrophilicity. Here we compare the mesh size and diffusion characteristics of PEG hydrogels by analyzing the diffusion of solutes with different, well-defined sizes over long and short time scales. Interestingly, one can tune the m...
متن کاملViral infection of human progenitor and liver-derived cells encapsulated in three-dimensional PEG-based hydrogel.
We have studied the encapsulation of human progenitor cells into 3D PEG hydrogels. Replication-incompetent lentivirus promoter reporter vectors were found to efficiently detect the in vivo expression of human hepatic genes in hydrogel-encapsulated liver progenitor cells. Similarly, hydrogel-encapsulated cells could be efficiently infected with hepatitis C virus, and progeny infectious virus cou...
