  • Publication number: 20200208291
    Abstract: Provided herein are methods for the controlled, independent modification of the surface of magnesium-based materials and compositions generated thereby. The methods allow for the alteration of multiple surface characteristics including generation of precise nanostructures, morphology, crystallography, chemical hybridizations and chemical composition for controlled bioresorption and/or increased biocompatibility, for example, osseointegration, hydroxyapatite formation, osseoconduction, cell adhesion, cell proliferation, enhanced local mechanical properties (elasticity, modulus, surface texture, porosity), hydrophobicity, hydrophilicity, steric hindrance, modulating-immuno response, anti-inflammatory properties and/or anti-bacterial properties.

  • Publication number: 20200197566
    Abstract: Provided herein are systems and methods for the controlled surface modification of a material substrate, including, for example, generation of nanostructures, crystallographic or morphologic alterations and the removal of defects, changes in chemical composition and bond structure and the creation of thermodynamic metastable states. The provided systems and methods utilize one or more directed energetic particle beams with independently controlled parameters (e.g. incident angle, fluence, flux, energy, species, etc.) to precisely and efficiently generate enhanced surface properties beyond those of conventional plasma kinetic roughening.

  • Publication number: 20200149145
    Abstract: Provided herein are methods for the controlled, independent modification of the surface of titanium-based materials and compositions generated thereby. The methods allow for the alteration of multiple surface characteristics including generation of precise nanostructures, morphology, crystallography and chemical composition for increased biocompatibility, for example, osseointegration, osseoconduction, cell adhesion, cell proliferation, mechanical properties (e.g. elasticity, modulus, surface texture, porosity), hydrophobicity, hydrophilicity, steric hindrance, anti-inflammatory properties and/or anti-bacterial properties.

  • Publication number: 20200129669
    Abstract: Provided herein are magnesium-based sponges and foams and methods for surface modification to enhance bioactivity. The magnesium-based sponges and foams may be useful as tissue or bone grafts which promote cellular adhesion and osseointegration and conduction, as well as various other biological functions including, for example, antibacterial properties, hydrophobicity or hydrophilicity and the ability to modulate immune response. The described sponges and foams have precise mechanical properties which are specifically designed for enhanced integration with surrounding tissue. The described magnesium-based materials are bioresorbable, allowing for the gradual, safe absorption of the material when exposed to bodily fluids.

  • Publication number: 20190292652
    Abstract: A method for fabricating structures includes on a substrate includes providing the substrate having a substrate surface, and providing a set of control parameters to an ion beam source and to a thermal source corresponding to a desired structure topology. The method further includes using directed irradiation synthesis to cause self-organization of a plurality of structures comprising at least one of the group of nanostructures and microstructures in a first surface area of the substrate by exposing the substrate surface to an ion beam from the ion beam source and to thermal particles from the thermal source. The ion beam has a first area of effect on the substrate surface, and the thermal particles has a second area of effect on the substrate surface. Each of the first area of effect and the second area of effect including the first surface area.
