OBJECTIVE To observe the effects of ionic dissolution products on nano-sized 58S bioactive glass (nano-58S) on proliferation and specific osteogenic genes expression in MG-63 cells. METHODS Ionic dissolution products were prepared by incubating nano-58S or sol-gel bioactive glass 58S (58S) particulates in Dulbecco's modified Eagle's medium (DMEM) at 1% w/v for 24 hr and filtrated through 0.22...

conclusions increasing the cu nanoparticles in bioactive glass samples leads to the release of cu2+, which has a positive effect on the antibacterial mechanism, as well as decreasing the cultured staphylococcus colonies found on the bioglasses. therefore, it seems that the nanocomposite/bioglass of cuo is a promising option for aerobic bacterial inhibitor systems in common bone implant infectio...

Background: Bioactive glasses 58S, are silicate-based materials containing calcium and phosphate, which dissolved in body fluid and bond to the bone tissue. This type of bioactive glass is highly biocompatible and has a wide range of clinical applications. Methods: The 58S glass powders were synthesized via sol-gel methods, using tetraethyl orthosilicate, triethyl phosphate, and calcium nitrate...

Bioactive glasses synthesized by the sol-gel technique possess many of the qualities associated with an ideal scaffold material for a bone graft substitute. In view of the potential clinical applications, we performed a detailed in vitro study of the biological reactivity of synthesized 58S bioactive glass containing-zinc, in terms of osteoblast morphology, proliferation, and deposition of a mi...

Graphene is a novel material and currently popular as an enabler for the next-generation nanocomposites. Here, we report the use of graphene to improve the mechanical properties of nano-58S bioactive glass for bone repair and regeneration. And the composite scaffolds were fabricated by a homemade selective laser sintering system. Qualitative and quantitative analysis demonstrated the successful...

poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (pbgha) and poly (lactide-co-glycolide)/ bioactive glass (pbg) nanocomposite coatings with bone. materials and methods: sol-gel derived 58s bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite nanoparticles were used to prepare the coatings. the nanocomposite coatings were characterized by ...
