Keywords: electrospinning, nanofibers, functionalization


Here we investigate the crucial step of protein functionalization for prototype polymer nanofibers. We compare different coating approaches for a target adhesion protein, including both physisorption and covalent binding methods relying on different functional linkers. Scanning electron microscopy, wettability measurements, Fourier-Transform infrared spectroscopy, protein quantification and cytotoxic assays are performed.
