Abstract | We synthesized a library of 50 poly(ethylene glycol) (PEG) derivatives to expand the extent of conjugation with biologically active molecules (biopolymers, peptides, drugs, etc.) and biomaterial substrates. The formation of PEG derivatives was confirmed with HPLC, 1H and 13C NMR. PEG derivatives were polymerized into networks in order to study the role of PEG and terminal functional groups in modulating the hydrophilicity of biomaterials and cell-biomaterial interaction. The resulting surface hydrophilicity and the number of adhered fibroblasts were primarily dependent on the PEG concentration with the molecular weight and the terminal functional group of PEG derivatives being less important. One of PEG derivatives, PEG-bis-glutarate, was utilized to link peptide sequences to gelatin backbone in the formation of novel biomedical hydrogels. PEG-peptide conjugates were characterized by mass spectroscopy. PEG-peptide modified gelatins were characterized by gel permeation chromatography. |
