A peptide – stainless steel reaction that yields a new bioorganic – metal state of matter

Peptide-based biocoatings for corrosion protection of stainless steel biomaterial in a chloride solution

“…It was demonstrated previously [13] that there is a chemical interaction of the peptide coatings with stainless steels, and the interaction can change the electronic state of the steel surface and produce a strong adhesion of the peptide to the steel. Fig.…”

“…In previous work, a series of peptides (K122-4) derived from the receptor-binding domain of the type IV pilin of Pseudomonas aeruginosa bacteria were identified, and the peptides effectively bind via a semi-covalent interaction to a variety of metallic materials including stainless steels [13,14]. It was found that these peptides demonstrate highly adhesive properties on the steels, and alter their surface characteristics by increasing the electron work function [13].…”

“…It was found that these peptides demonstrate highly adhesive properties on the steels, and alter their surface characteristics by increasing the electron work function [13]. Furthermore, peptides synthesized using D-amino acids to create enantiomeric and retroinverso forms were found to be extremely durable and proteaseresistant when bound to surfaces such as stainless steels [15,16].…”

Immobilization of epidermal growth factor on titanium and stainless steel surfaces via dopamine treatment

“…In addition to surface modifications aimed at preventing biofouling [1,5,6], extracellular matrix, active peptides, or derivatives have been immobilized on metals to promote cell adhesion [7][8][9][10][11][12][13].…”

A Facile Method to Prepare a Hydrophilic/Hydrophobic Metal Surface by Peptide

“…By comparison, we can see that there were three obvious peaks in it. The peak that appeared around 2800–3000 cm −1 [29,31] was corresponding to saturated C-H stretching vibration. It should be alkane.…”
