文摘
- •
A self-assembling peptide (SAP) was covalently immobilized of on a flat silicon surface.
- •
A physisorbed SAP layer was grown on top of the covalently immobilized peptide layer.
- •
Molecular order and orientation of the peptide overlayer on the flat silicon surface were determined by NEXAFS spectroscopy.
- •
RAIR spectroscopy allowed to determine that the peptide secondary β-sheet structure is retained.
