  • Publication number: 20100003296
    Abstract: The present invention also provides a method for making the antimicrobial plant fibers. The characteristic of the method is no need of additional reducing agent. The present invention provides plant fibers with antimicrobial effects. The antimicrobial antifungal effect of the fibers is derived from nanosilver particles (diameter between 1 and 100 nm) which are attached to the fibers. The fibers which are made of cotton, linen, blending fibers, or any combination thereof. The fibers can be used to make yarn cloth to be used particularly for treating patients with burns or wound. The cloth made from the antimicrobial fibers can be further used to make clothes such as underwears, socks, shoe cushions, shoe linings, bed sheets, pillow cases, towels, women hygiene products, laboratory coats, and medical robes.

  • Patent number: 6979491
    Abstract: The present invention provides a yarn with antimicrobial effects. The antimicrobial antifungal effect of the yarn is derived from nanosilver particles (diameter between 1 and 100 nm) which are adhered to the yarn. The yarn contains fibers which are made of cotton, linen, silk, wool, leather, blending fabric, synthetic fiber, or any combination thereof. The yarn can be used to make cloth to be used particularly for treating patients with burns or wound. The cloth made from the antimicrobial yarn can be further used to make clothes such as underwears, socks, shoe cushions, shoe linings, bed sheets, pillow cases, towels, women hygiene products, laboratory coats, and medical robes. The present invention also provides a method for making the antimicrobial yarn.

  • Publication number: 20030185889
    Abstract: The present invention provides a colloidal nanosilver solution which contains nanosilver particles having diameters between 1 nm and 100 nm. The silver content in the colloidal solution is between 0.001% to 0.4% by weight. The colloidal nanosilver solution also contains a gelling agent which includes, but is not limited to, starch or its derivative, cellulose or its derivative, polymer or copolymer of acrylate or acrylate derivative, polyvinyl pyrrolidone, alginic acid, and xanthogenated gel. The present invention also provides a method for making the colloidal nanosilver solution. The colloidal nanosilver solution prepared by this method does not contain any toxic or impure substances.

  • Publication number: 20020051823
    Abstract: The present invention relates to nanosilver-containing antibacterial and antifungal granules (“NAGs”). The NAGs have longlasting inhibitory effect on a broad-spectrum of bacteria and fungi, which include, but are not limited to, Escherichia coli, Methicillin resistant Staphylococcus aureus, Chlamydia trachomatis, Providencia stuartii, Vibrio vulnificus, Pneumobacillus, Nitrate-negative bacillus, Staphylococcus aureus, Candida albicans, Bacillus cloacae, Bacillus allantoides, Morgan's bacillus (Salmonella morgani), Pseudomonas maltophila, Pseudomonas aeruginosa, Neisseria gonorrhoeae, Bacillus subtilis, Bacillus foecalis alkaligenes, Streptococcus hemolyticus B, Citrobacter, and Salmonella paratyphi C. The NAGs contain ground stalk marrow of the plant Juncus effuses L. which has been dispersed with nanosilver particles. The nanosilver particles are about 1-100 mn in diameter. Each of the nanosilver particles contain a metallic silver core which is surrounded by silver oxide.
