Zusammenfassung:
Growth and deposition of unwanted bacteria on implant metal alloys affect their use as biomedical samples. Monitoring any bacterial biofilm
accumulation will provide early countermeasures. For a reliable antifouling strategy we prepared nitinol (NiTi) thin films on Ti-derived substrates by
using a pulsed laser deposition (PLD)method. As themicrostructure ofTi-alloy is dictated by the tensile strength, fatigue and the fracture toughness we
tested the use of hydrogen as an alloying element. X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM)
investigated the crystalline structure, chemical composition and respectively the surface morphology of the nitinol hydrogen and hydrogen-free
samples. Moreover, the alloys were integrated and tested using a cellular metric and their responses were systematic evaluated and quantified. Our
attractive approach is meant to select the suitable components for an effective and trustworthy anti-fouling strategy. A greater understanding of such
processes should lead to novel and effective control methods that would improve in the future implant stability and capabilities.
