Sol-gel derived AgMgO films for antibacterial and bioactive surface modification of niobium metal

Silver-containing MgO (AgMgO) films with the Ag/Mg molar ratio of 0, 0.3%, 1%, 3% and 6%, respectively were sol-gel coated on niobium metal to improve its antibacterial property and bioactivity, and niobium had been alkali pretreated to increase the film thickness. Sodium niobate nanofibers or nanobelts are formed at the surface of alkali treated niobium. For the coated samples, thick and rough Nb2O5 layers are grown due to oxidation of niobium...
