AB  - The present paper is focused on a study regarding the possibility of obtaining 
      hydroxyapatite-silver nanoparticle coatings on porous polyurethane scaffold. The 
      method applied is based on a combined strategy involving hydroxyapatite 
      biomimetic deposition on polyurethane surface using a Supersaturated 
      Calcification Solution (SCS), combined with silver ions reduction and in-situ 
      crystallization processes on hydroxyapatite-polyurethane surface by sample 
      immersing in AgNO3 solution. The morphology, composition and phase structure of 
      the prepared samples were characterized by scanning electron microscopy coupled 
      with energy dispersive X-ray spectroscopy (SEM-EDX), X-ray diffraction (XRD), 
      UV-Vis spectroscopy and X-ray photoelectron spectroscopy (XPS) measurements. The 
      data obtained show that a layer of hydroxyapatite was deposited on porous 
      polyurethane support and the silver nanoparticles (average size 34.71 nm) were 
      dispersed among and even on the hydroxyapatite crystals. 
      Hydroxyapatite/polyurethane surface acts as a reducer and a stabilizing agent for 
      silver ions. The surface plasmon resonance peak in UV-Vis absorption spectra 
      showed an absorption maximum at 415 nm, indicating formation of silver 
      nanoparticles. The hydroxyapatite-silver polyurethane scaffolds were tested 
      against Staphylococcus aureus and Escherichia coli and the obtained data were 
      indicative of good antibacterial properties of the materials.
