*2.7. Scanning Electron Microscopy*

Imaging of the uncoated and pDA-coated surfaces was performed on a Zeiss Supra 55VP scanning electron microscope (Carl Zeiss Ltd., Zeiss House, Cambridge, UK). All measurements were conducted on samples coated with ≈1 nm of the electrodeposited carbon film. A 10 kV electron beam and various magnifications were used.
