A Versatile Star PEG Grafting Method for the Generation of Nonfouling and Nonthrombogenic Surfaces
Figure 3
XPS high-resolution C1s scans of aminated glass (a) before and (b-e) after star PEG grafting at various coupling concentrations (0.55, 1.66, 5, and 15% w/v). Note that the relative intensity of the C–O peak increased with the PEG coupling concentration; (f) Overlay spectra of 15% PEG-modified on unmodified aminated surface.
