IJMS | Free Full-Text | Aluminum Foil vs. Gold Film: Cost-Effective
In the case of aluminum vs. gold substrates, a more important factor than Van der Waals interactions contributing to the stronger binding of hIgG and/or hIgG to gold rather than aluminum is probably the higher energy of adsorption of sulfur on gold (e.g., 0.7 eV for cysteine/Au) in comparison to that on aluminum (e.g., 0.5 eV for thiophene/Al
