Purpose To evaluate the polymer doped rods behavior with bioactive glass and hydroxyapatite for possible application as a fracture fixing method. Methods Twenty eight Rattus norvegicus Wistar underwent bone defect for access to the femoral medullary canal and distributed into three experimental groups: group A - doped castor bean polymer with bioactive glass; group B - castor bean polymer and; ...

BACKGROUND In recent years, bioceramics have been favored by biomaterials scientists and researchers. Due to their special and distinctive features, bioactive glass and hydroxyapatite possess a higher place among different types of bioceramics. METHOD In this study, the effect of 63S bioactive glass and bone-derived hydroxyapatite particles on the proliferation of human bone-marrow stem cells...

This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...

Supramolecular nanostructures covered with bioactive functional molecules have been actively explored as promising materials in the field of biotechnology. Recent advances in nano-sized chemistry have made it possible to fabricate various kinds of nanostructures with tailor-made nanostructural properties. This, combined with appropriate bioactive functionalization, has led to the successful uti...

In this study, we prepared nano-hydroxyapatite/polyamide 66/glass fibre (n-HA/PA66/GF) bioactive bone screws. The microstructure, morphology and coating of the screws were characterised, and the adhesion, proliferation and viability of MC3T3-E1 cells on n-HA/PA66/GF scaffolds were determined using scanning electron microscope, CCK-8 assays and cellular immunofluorescence analysis. The results c...

The cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. This study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder:andmicropowder. Human HGF1-PI53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/mL concentrations of the two bioactive...

Diatoms are single-celled algaes that make photonic-crystal-like silica shells or frustules with hierarchical micro- & nano-scale features consisting of two-dimensional periodic pores. This article reports the use of diatom frustules as an integration platform to enhance localized surface plasmon resonances of self-assembled silver nanoparticles (NPs) on the surface of diatom frustules. Theoret...
