Thin films of hydroxyapatite (HA) and silver- doped HA were synthesized using KrF excimer laser deposition. Material was ablated from one target composed from silver and HA segments. Layers properties as silver content, structure, color, FTIR spectra and antibacterial properties (gram positive Bacilus substilis) were measured. Silver concentration in HA layers of 0.06 at%, 0.3 at%, 1.2 at%, 4.4 at%, 8.3 at% and 13.7 at% was detected. The antibactericidal efficacy changed with silver dopation from 71% to 99.9 %. The focus is on investigation of minimum Ag concentration needed to reach high antibactericidal efficacy.
