Abstract:

<p>An Ag:HAp (x(Ag) = 0.5) powder was deposited by thermal evaporation technique as coating on a silicon substrate previously covered with a polydimethylsiloxane (PDMS) layer. The Ag: HAp-PDMS layers were characterized by Scanning ElectronMicroscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), and Fourier Transform Infrared Spectroscopy (FT-IR). By infrared spectroscopy analysis, the phase composition of the Ag: HAp-PDMS layers was investigated. The antimicrobial activity of Ag: HAp-PDMS layers was tested against Escherichia coli, Staphylococcus aureus, and Candida albicans microbial strains. The microbial activity decreases significantly for the surveyed time intervals on Ag: HAp-PDMS layers.</p>
