The contact angle of some biological liquids was investigated on different biocompatible surfaces and nanoparticles were employed to improve their wetting ability. Biocompatible nanoparticles based on titanium, silver and gold were prepared using the technique of the pulsed laser ablation in liquids. The nanoparticles were characterized in size, shape, coalescence and concentration in solutions. Solid biocompatible substrates based on polyethylene, hydroxyapatite and titanium were employed as simulation of prosthetic surfaces. Measurements of contact angle were performed in different biological solution, including the human blood, with respect to the distilled water, without and with the use of the metallic nanoparticles at concentration of the order of 80-370 μg/ml.
