In vitro and in vivo osteogenic potential of niobium‐doped 45S5 bioactive glass: A comparative studyJournal of Biomedical Materials Research Part B: Applied Biomaterials
In vitro and in vivo experiments were undertaken to evaluate the solubility, apatite‐forming ability, cytocompatibility, osteostimulation, and osteoinduction for a series of Nb‐containing bioactive glass (BGNb) derived from composition of 45S5 Bioglass. Inductively coupled plasma optical emission spectrometry (ICP‐OES) revealed that the rate at which Na, Ca, Si, P, and Nb species are leached from the glass decrease with the increasing concentration of the niobium oxide.
Origin of micro-scale heterogeneity in polymerisation of photo-activated resin compositesNature Communications
Photo-activated resin composites are widely used in industry and medicine. Despite extensive chemical characterisation, the micro-scale pattern of resin matrix reactive group conversion between filler particles is not fully understood. Using an advanced synchrotron-based wide-field IR imaging system and state-of-the-art Mie scattering corrections, we observe how the presence of monodispersed silica filler particles in a methacrylate based resin reduces local conversion and chemical bond strain in the polymer phase.
Photo-polymerisation variables influence the structure and subsequent thermal response of dental resin matricesDental Materials
The structure of the polymer phase of dental resin-based-composites is highly sensitive to photo-polymerisation variables. The objective of this study was to understand how different polymer structures, generated with different photo-polymerisation protocols, respond to thermal perturbation.
Evaluation of effectiveness of 45S5 bioglass doped with niobium for repairing critical‐sized bone defect in in vitro and in vivo modelsJournal of Biomedical Materials Research Part A
Here, we investigated the biocompatibility of a bioactive sodium calcium silicate glass containing 2.6 mol% Nb2O5 (denoted BGPN2.6) and compare the results with the archetypal 45S5 bioglass. The glass bioactivity was tested using a range of in vitro and in vivo experiments to assess its suitability for bone regeneration applications. in vitro studies consisted of assessing the cytocompatibility of the BGPN2.6 glass with bone‐marrow‐derived mesenchymal stem cells (BM‐MSCs).
Insight into the atomic scale structure of CaF2-CaO-SiO2 glasses using a combination of neutron diffraction, 29Si solid state NMR, high energy X-ray diffraction, FTIR, and XPSBiomedical Glasses
Bioactive glasses are important for biomedical and dental applications. The controlled release of key ions, which elicit favourable biological responses, is known to be the first key step in the bioactivity of these materials. Properties such as bioactivity and solubility can be tailored for specific applications. The addition of fluoride ions is particularly interesting for dental applications as it promotes the formation of fluoro-apatite. To date there have been mixed reports in the literature on how fluorine is structurally incorporated into bioactive glasses.
