Description
Summary:In the present work, various concentrations of strontium ions loaded titanium dioxide nanorods and common titanium dioxide nanorods (control) were synthesized by electrochemical anodization technique to get the implant with superior bioactivity. Cell viability and antibacterial efficacy studies were estimated using MTT assay and solid agar medium. The characterisation results confirmed that Sr 2+ was successfully incorporated into TiO 2 nanorods. Compared with common TiO 2 nanorods (control), Sr 2+ loaded TiO 2 nanorods showed higher surface roughness, adhesion strength, and water wetting angle. MTT assay showed better cell response on Sr-TiO 2 nanorod surface as compared to control and the antibacterial test showed that Sr 2+ loaded TiO 2 nanorods have superior antibacterial activity against pathogenic bacterial strain E. coli and S. aureus . Sr 2+ incorporated TiO 2 nanorod arrays can be used as a potential candidate for hard tissue implant applications.
