Antibacterial effect of morphous (poly-crystalline) and amorphous (glass) nano-bioactive glass 45S5 on Streptococcus mutans
Objective: Bioactive glass 45S5 is a surface reactive glass-ceramic biomaterial, developed in 1969. BAG 45S5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. The aim of this study was to evaluate the antibacterial activity and determine MIC and MBC values of nano-BAG45S5 on Streptococcus mu...
متن کاملFabrication of 45s5 Bioactive Glass-polycaprolactone Composite Scaffolds
Tissue engineering is a multi-disciplinary field, which aims to apply innovative biomaterials to replace or restore ill or damaged tissues of the human body, such as skin and bones. In particular, porous scaffolds are used as temporary 3D templates to support cell attachment and proliferation during the spontaneous regeneration of natural tissues and this approach is particularly promising for ...
متن کاملFemtosecond laser induced surface nanostructures on copper
This study demonstrated circular surface nanostructures and femtosecond laser-induced periodic surface structures (FLIPSS) for copper produced by a Ti:Sapphire femtosecond laser beam of wavelength 800 nm and duration 120 fs. The circular textured nanostrucres could be created by a single laser pulse. The nanostructures in the center of the heated spot diminish as laser fluence increases and a c...
متن کاملElastic Properties of substituted 45S5 Bioactive Glasses and Glass - Ceramics
CuO, Fe2O3, MnO2 and ZnO substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified using X ray diffraction (XRD) analysis. Density and ultrasonic wave velocities of bioactive glasses and glass ceramics were measured and u...
متن کامل45S5 bioactive glass surface charge variations and the formation of a surface calcium phosphate layer in a solution containing fibronectin.
This study investigated the effect of fibronectin adsorption on surface charge variations and calcium phosphate (Ca-P) layer formation kinetics on the surface of 45S5 bioactive glass (BG). We hypothesize that the adsorption of fibronectin on BG changes the surface charge and alters the kinetics of Ca-P layer formation on the glass surface. The charge at a material's surface modulates surface ch...
