Abstract

While electrospun fibers are of interest as scaffolds for tissue engineering applications, nonspecific surface interactions such as protein adsorption often prevent researchers from controlling the exact interactions between cells and the underlying material. In this study we prepared electrospun fibers from a polystyrene-based macroinitiator, which were then grafted with polymer brushes using surface-initiated atom transfer radical polymerization (SI-ATRP). These brush coatings incorporated a trimethylsilyl-protected PEG-alkyne monomer, allowing azide functional molecules to be covalently attached, while simultaneously reducing nonspecific protein adsorption on the fibers. Cells were able t..
