Table 2 The morphology of ELP grafted on gold is impacted by hydrophobicity/charge, rearrangement kinetics and AEF. The conditions of peptide grafting experiments are described (peptide type, assembly voltage, and presence of salt) along with their impact on the rearrangement constant (kt) and grafted ELP morphology.
