We revealed significant changes in the topography, a decrease in the surface zeta potential from -63 to -75 mV after the oxygen-plasma treatment and an increase after ammonia plasma treatment from -63 to -45 mV at a pH of 7.4. Investigations into the NIH 3T3 fibroblast adhesion and growth demonstrated the best cell vitality and a higher cell number for the ammonia plasma treatment at 150W.en530journal article
