Fabrication 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 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 کاملAntibacterial 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 کاملPolycationic peptides from diatom biosilica that direct silica nanosphere formation.
Diatom cell walls are regarded as a paradigm for controlled production of nanostructured silica, but the mechanisms allowing biosilicification to proceed at ambient temperature at high rates have remained enigmatic. A set of polycationic peptides (called silaffins) isolated from diatom cell walls were shown to generate networks of silica nanospheres within seconds when added to a solution of si...
متن کاملEvaluation of cytotoxicity and mechanical properties of fluorapatite-45S5 bioactive glass nanocomposite
The purpose of this study was to fabricate and characterize nanocomposite powder from 45S5 bioactive glass/ fluorapatite. Nanocomposites containing 10, 15 and 20 wt.% of fluorapatite were synthesized by sol-gel method. XRD and FT-IR analyses were used to characterize and evaluate the produced nanocomposites. The results of XRD and FT-IR analysis indicated the successful synthesis of high purity...
