Název v původním jazyce

Mechanical and antibacterial properties of silver doped diamond-like carbon films

Popis výsledku v původním jazyce

Silver doped diamond-like carbon (Ag-DLC) were deposited on silicon (Si 100) and titanium substrates (Ti-6Al-4V) by pulsed laser ablation (PLD) for laser energy density 10 J*cm -2 using KrF excimer laser and segmented target (graphite : silver - 7:1, 3:1, 5:3).The mechanical and antibacterial properties of Ag-DLC films have been investigated. The composition was analyzed using wavelength-dependent X-ray spectroscopy. The topology and surface properties as roughness of films were studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Mechanical properties of DLC films with various silver content were evaluated. Hardness (reduced Young's modulus) was determined by nanoindentation. Films adhesion was studied using scratch testand with concentration of silver decreasing. In vivo measurement (using gram positive and negative bacteria) of antibacterial properties of the Ag-DLC films. This result opens further possibility for application of Ag-DLC films in medici
