Silver-loaded textile compound and silver-loading process thereof
The invention discloses a silver-loaded textile compound and a sliver-loading process thereof. The silver-loaded textile compound comprises a silver-loaded textile body, wherein the silver-loaded textile is silver sesquioxide. The process steps are as follows: (1) placing textile in tetrasilver tetroxide solution, keeping the temperature of the mixture within 40 DEG C to 95 DEG C for 20-120 minutes; (2), getting out and drying the textile for 5-150 minutes within 70 DEG C to 150 DEG C; (3), placing the dried textile in the solution of sodium (potassium) hydroxide and sodium (potassium) persulfate, keeping the temperature of the solution within 40 DEG C to 95 DEG C for 10-100 minutes; and (4), getting out and washing the textile 2-3 times with water, drying the washed textile within 70 DEG C to 150 DEG C to acquire the silver-loaded textile compound. The invention has the advantage that the silver sesquioxide loaded on the silver-loaded textile compound is a trivalent silver oxide with higher positive electricity, which is formed by the steps of bonding tetrasilver tetroxide with fabric to form a coordination bond, and then oxidizing the coordination bond; thus the silver sesquioxide is bonded with fiber fabric firmer to achieve stronger bactericidal action.

Tetrasilver-tetraoxide-loaded silica antibacterial material and preparation method as well as application thereof
The invention relates to a silver-based bactericide, and in particular relates to a tetrasilver-tetraoxide-loaded silica antibacterial material and a preparation method as well as an application thereof. Tetrasilver tetraoxide is uniformly distributed on the gap surface of silica, wherein each 1000g of the antibacterial material contains 0.027 to 0.94g of tetrasilver tetraoxide. The formed tetrasilver tetraoxide crystals are ultra-fine crystals which are uniformly distributed on the surface of silica, and are uniform in granularity, large in specific surface area, high in surface atom ratio as well as strong in chemical adsorption capacity and chemical reaction performance. Therefore, bacteria and viruses can be easily adsorbed and instantaneously killed under the cooperative action of the tetrasilver tetraoxide crystals; and the performance of silica for adsorbing organic toxic and harmful substances is enhanced at the same time. In addition, active groups exist on the surfaces of the tetrasilver tetraoxide crystals, thereby being convenient for further modification of the functional groups. The tetrasilver-tetraoxide-loaded silica antibacterial material is wide in application range and can be applied to the fields of water treatment, fiber products, coating materials, plastic and the like.

Atlanta Metropolitan State College, 1630 Metropolitan Parkway, SW. Atlanta, GA, USA

[ PDF ]

Abstract

Current emphasis on elimination of the HIV/AIDS epidemic challenges researchers to assess the efficacy of alternative treatment modalities. Previous studies have been conducted using different silver preparations such as silver nitrate (AgNO3) and silver oxide hydrosol (Ag404) to treat HIV/AIDS patients. These studies did not use nanoparticles and used small sample sizes. Nanoparticle preparations hold particular promise because of their ability to enhance surface coverage. The present investigation is designed to test the efficacy of silver nanoparticle preparations using a pretest- posttest methodology. This research proposal is intended to increase awareness of a complimentary approach to HIV treatment and to stimulate future silver nanoparticle research.

Method for treating blood borne viral pathogens such as immunodeficiency virus
US 6066489


Abstract

A method and apparatus for destroying blood borne pathogens is disclosed which utilizes a low intensity direct current to generate positive particles from various metals which destroy viral pathogens. A first electrode comprised of a metal such as silver is inserted into a patient's venous system. Then, a second electrode is placed on the patient's exterior in the vicinity of the first electrode. A low intensity direct current is applied to the first metal electrode which releases silver cations to be bonded to the virus, resulting in the denaturing of the virus. The first electrode is placed in the venous system of the infected patient via a catheter.
