The mixed antibacterial glass achieves antibacterial effect by releasing silver ions, and contains an antibacterial glass which shows alkalinity when dissolved, and another antibacterial glass which shows acidity when dissolved, the silver ion elution amounts from the antibacterial glasses showing alkalinity or acidity being within certain ranges as measured under certain conditions, the compounding amount of the antibacterial glass showing alkalinity being from 10 to 100 parts by weight with reference to 100 parts by weight of the antibacterial glass showing acidity, and the total silver ion elution amount being within a certain range as measured under certain conditions.

  • Patent number: 9011665
    Abstract: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer is grown by anodizing at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange. This produces a significantly harder surface than anodizing at low voltage, and generates pits containing ion-absorbing material.

  • Publication number: 20150104488
    Abstract: The invention relates to a composite material with at least one supporting material and at least one antimicrobial agent from the group of metals and metal compounds. The composite material comprises at least one hydrophilizing agent which increases the wettability of the surface of the composite material with water in comparison to the wettability of the surface of the composite material without the addition of the hydrophilizing agent. The invention further relates to a method for producing a composite material.

  • Patent number: 9005663
    Abstract: An exemplary embodiment of the invention is a method for making silver nanoparticles, and includes steps of reacting a silver salt with a phosphene amino acid to make silver nanoparticles. Exemplary phosphene amino acids include trimers, with a particular example being a trimeric amino acid conjugate containing one phosphene group. In an exemplary method of the invention, the silver nanoparticles may be produced in timer periods of less than about 30 minutes, and at temperatures of less than about 40° C. Other methods of the invention are directed to methods for stabilizing silver nanoparticles.

  • Patent number: 8999367
    Abstract: Bioabsorbable substrates having antimicrobial metal ion coatings that are well suited for implantation in to a subject's body to treat and/or prevent infection. In particular, described herein are flexible bioabsorbable filaments that are coated with an anodic metal (e.g., silver and/or zinc and/or copper) that is co-deposited with a cathodic metal (e.g., palladium, platinum, gold, molybdenum, titanium, iridium, osmium, niobium or rhenium) on the filament so that the anodic metal is galvanically released as antimicrobial ions when the apparatus is inserted into a subject's body. The anodic metal may be at least about 30 percent by volume of the coating.

  • Publication number: 20150093453
    Abstract: This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s).
