Mesoporous bioactive glasses have been widely investigated for applications in bone tissue regeneration and, more recently, soft repair and wound healing. In this study we produced mesoporous glass nanoparticles (MBGNs) based on the SiO2-CaO system. With intention of adding subsidiary biological function, MBGNs were doped with Zn2+ ions. Zn-MBGNs 8 mol% ZnO content synthesized via microemulsion assisted sol-gel method. The particles homogeneous shape size. They exhibited spherical shape,...
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-ray diffraction confirmed amorphous nature nanoparticles. The chemical compositions all samples...
We report the successful preparation and characterization of chitosan-Zn complex (ChiZn) in form films, intended to enhance biological performance chitosan by presence Zn as antibacterial agent biologically active ion. The influence chelation on morphology structure was assessed scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy infrared spectroscopy. biodegradability study ChiZn showed a sustained release up 2 mg/mL. No toxic response observed toward stromal cell...
Borate 1393-B3 bioactive glasses doped with ZnO or Ga2O3 (1, 3, and 6% mol) were produced by conventional melt quenching. All showed in-vitro bioactivity in simulated body fluid (SBF). For the first time, dissolution behavior of both phosphate-buffered saline (PBS) cell culture medium was investigated. The ion release rate increased compared to that PBS solution. tested glass compositions, including parent glass, antibacterial effect against S. aureus E. coli. incorporation Zn Ga enhanced...
Co-substitution of magnesium and copper (up to 2 mol%) in a silicate mesoporous glass has potential stimulating new tissue formation by Cu Mg ion delivery enhancing multiple biological features for bone regeneration.
This work verifies the applicability of two‐stage sintering as a means suppressing final stage grain growth submicrometer alumina. The first heating step should be short at relatively high‐temperature (1400°–1450°C) in order to close porosity without significant growth. second temperatures around 1150°C facilitates further densification with limited Fine‐grained alumina relative density 98.8% and size 0.9 μm was prepared by sintering. A standard process resulted ceramics identical 1.6 μm.
Mesoporous bioactive glass nanoparticles (MBGNPs) are attracting significant attention as suitable materials for multifunctional biomedical applications. In this study, cerium was incorporated into MBGNPs using two different approaches. the first approach, added to system directly during synthesis, while in second as-synthesized via template ion-exchange method. The influence of method synthesis on physicochemical properties examined by SEM, TEM, XRD, FTIR, and N2 adsorption-desorption...

Abstract Hybrid glasses derived from meltable metal‐organic frameworks (MOFs) have emerged as a new class of amorphous materials. Combining the porosity MOFs with processing ability glasses, they are thought to enable wholly range functional compounds.
