From: Grafting of short elastin-like peptides using an electric field
AFM images of grafted ELP show that charge/hydrophobicity and AEF impact morphology. Height and phase contrast images of (a) uncharged ELP and (b) (−)charged ELP grafted on gold QCM sensors at + 0.3 V AEF in DI water, − 0.3 V AEF, with no AEF in DI water, and with no AEF in 0.5 M NaCl. A bare gold QCM sensor is provided for reference. Example morphologies are outlined in yellow. All voltages are vs. a Ag/AgCl reference.
