Functionalization of a chemically treated Ti6Al4V-ELI alloy with nisin for antibacterial purposes

Nano-topography and functionalization with the synthetic peptoid GN2-Npm9 as a strategy for antibacterial and biocompatible titanium implants

“…Lastly, as the authors already described in previous findings related to the antimicrobial peptide Nisin [ 60 , 61 ], the functionalization through a chemisorption mechanism is advantageous both in comparison with physisorption, which is a weak and poorly controlled bond with the surface, and covalent grafting, that does not allow the release of the antibacterial agent (such as the peptoid, in this case), resulting in a weak antibacterial effect.…”

Effect of Electrolytic Plasma Polishing on Surface Properties of Titanium Alloy

“…The composition of PBS phosphate buffer (per liter, dissolved in distilled water) was as follows: 0.24 g KH 2 PO 4 , 1.44 g Na 2 HPO 4 , 8 g NaCl, 0.2 g KCl. The exposure area of the working electrode in the electrolyte was 1 cm 2 . The open circuit potential (OCP) of 1800 s was first measured and recorded to ensure the stability of the samples in PBS solution.…”

“…Ti6Al4V, as an α + β biphasic titanium alloy, is widely utilized in aerospace, defense, and biomedical fields due to its comprehensive performance [1][2][3]. Especially in the biomedical field, Ti6Al4V alloy is used for the manufacturing of bone implants, joint prostheses, and artificial heart valves due to its characteristics such as low density, high strength-to-weight ratio, low elastic modulus, corrosion resistance, and excellent biocompatibility [4,5].…”
