47. In our previous work, we also examined a peptide 42 amino acids long, that is with intermediate length.19 We found that its stability actually decreased upon adsorption suggesting that the effect of adsorption on peptide stability may differ substantially, depending on the structure, structural stability, and flexibility of the free peptide. Here, we restrict our conclusions to peptides whose stability increases upon adsorption.
