  • Publication number: 20230365418
    Abstract: Disclosed herein is a method comprising a) forming a mixture comprising: i) an aromatic nitrogen-containing compound, ii) a saccharide; and iii) a silica precursor; b) adding an amount of water to the mixture to initiate a condensation reaction; and c) precipitating a plurality of amorphous silica-based nanoparticles. Also disclosed herein is a plurality of amorphous silica-based nanoparticles, scaffolds, and devices comprising the same, in addition to methods of using the same.

  • Publication number: 20210138120
    Abstract: Amorphous SiOx (SiO2), SiONx, silicon nitride (Si3N4), surface treatments are provided, on both metal (titanium) and non-metal surfaces. Amorphous silicon-film surface treatments are shown to enhance osteoblast and osteoblast progenitor cell bioactivity, including biomineral formation and osteogenic gene panel expression, as well as enhanced surface hydroxyapatite (HA) formation. A mineralized tissue interface is provided using the amorphous silicon-based surface treatments in the presence of osteoblasts, and provides improved bone cell generation/repair and improved interface for secure attachment/bonding to bone. Methods for providing PEVCD-based silicon overlays onto surfaces are provided. Methods of increasing antioxidant enzyme (e.g., superoxide dismutase) expression at a treated surface for enhanced healing are also provided.

  • Patent number: 10828393
    Abstract: Disclosed are compositions, methods and processes for fabricating and using a device or other implement including a surface or surfaces having a nanoscale or microscale layer or coating of Si—O—N—P. These coatings and/or layers may be continuous, on the surface or discontinuous (e.g., patterned, grooved), and may be provided on silica surfaces, metal (e.g., titanium), ceramic, and combination/hybrid materials. Methods of producing an implantable device, such as a load-bearing or non-load-bearing device, such as a bone or other structural implant device (load-bearing), are also presented. Craniofacial, osteogenic and disordered bone regeneration (osteoporosis) uses and applications of devices that include at least one surface that is treated to include a nanoscale or microscale layer or coating of Si—O—N—P are also provided. Methods of using the treated and/or coated devices to enhance enhanced vascularization and healing at a treated surface of a device in vivo, is also presented.
