A high-density PEG interfacial layer alters the response to an EGF tethered polydimethylsiloxane surface

Previously, epidermal growth factor (EGF)-modified surfaces have shown promise in supporting cellular growth and adhesion on synthetic polymeric substrates. Surfaces prepared using a novel modification technique were investigated in the current work for their ability to support corneal epithelialization, important to the integration of a synthetic artificial cornea. EGF could be tethered to PDMS surfaces via a high-density, hetero-bifunctional …
