In recent years, mesoporous bioactive glass nanoparticles (MBGNPs) have generated great attention in biomedical applications. this study, cerium and gallium doped MBGNPs were prepared by microemulsion assisted sol-gel method the binary SiO2-CaO system. with spheroidal pineal shaped morphology obtained. Nitrogen sorption analysis elucidated structure of synthesized high specific surface area. X-...

Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS-bioactive glass fiber (F18)-reinforced composite was developed and cha...

This paper will report on research which aims to generate bone replacement components by processing bioactive glass-ceramic powders using indirect selective laser sintering. The indirect SLS route has been chosen as it offers the ability to tailor the shape of the implant to the implantation site, and two bioactive glass ceramic materials have been processed through this route: apatite-mullite ...

We investigated the interwire distance dependence on the growth kinetics of vertical, high-yield InAs nanowire arrays on Si 111 grown by catalyst-free selective area molecular beam epitaxy MBE . Utilizing lithographically defined SiO2 nanomasks on Si 111 with regular hole patterns, catalyst-free and site-selective growth of vertically 111 -oriented InAs nanowires was achieved with very high yie...

The objective of our work is to improve the osseointegration of titanium (and its alloys) used in dental and orthopedic applications. To do this, we have been coating these metals with glasses whose compositions are based upon Bioglass®, which is a bioactive glass developed by Hench et al. Bioactive glasses have the property of forming an apatite layer (and therefore can chemically bond to bone...

There is accumulating evidence that strontium-containing biomaterials have positive effects on bone tissue repair. We investigated the in vitro effect of a new Sr-doped bioactive glass manufactured by the sol-gel method on osteoblast viability and differentiation. Osteoblasts isolated from foetal mouse calvaria were cultured in the presence of bioactive glass particles; particles were undoped (...
