This work shows the enhancement of the antibacterial process by single crystals of TiO2-B nano-wires in comparison to anatase nano-particles.
The preparation ofthe single crystal of TiO2-B nano-wires was performed by one-step hydrothermal reaction at 130ºC among particles of pure anatase and NaOH aqueous solution by 6 days of reaction and calcined at 500ºCin air by 24h.
The monoclinic phase of titanium dioxide (TiO2-B) was characterized by Raman spectroscopy, atomic force microscopy (AFM), XRD, SEM and TEM. The antibacterial process of TiO2-Bnano-wires and anatase nano-particles was studied on pure culture of Escherichia Coli (E. coli), the results indicated that E. coli decrease faster for UV illuminated TiO2-B nanowires than UV illuminatedanatase nano-particles.
Antibacterial properties of TiO2-B nanowires allow new aplications on industrial field as air cleaner, paint revestiments. Also, it has application in medical industry asan antibacterial protection.
