Publication number: 20100291169Abstract: Anionic polyelectrolytes are used as binding agents to reduce the solubility of cationic antimicrobial polyelectrolytes. Ionic attraction between the anionic stabilizing polyelectrolytes and the antimicrobial cationic polyelectrolytes results in formation of a polyelectrolyte complex (PEC). A treatment liquid comprising a stable colloid, suspension, dispersion, solution, coacervate, or emulsion of the PEC in an aqueous carrier is used to treat an article, thus coating, infiltrating, or infusing the PEC onto or into the article. Subsequent drying results in an antimicrobial article wherein the PEC is bound to the article and is significantly less prone, relative to either of the component polyelectrolytes, to being washed, leached, leaked, extracted, or migrated from the antimicrobial article during use, or when exposed to aqueous fluids or solvents.Type: ApplicationFiled: July 2, 2010Publication date: November 18, 2010Applicant: QUICK-MED TECHNOLOGIES, INC.Inventors: William Toreki, David N.

Publication number: 20100255178Abstract: A system and method of enhancing the antimicrobial and biofilm-resistant efficacy of surfaces that have cationic polyelectrolytes nonleachably bound thereto in order to impart antimicrobial activity to the surface. The system for enhancing antimicrobial efficacy involves brushing, dipping, wiping, spraying, or storing the surface in a solution containing citrate ion. The method involves treatment of the surface with a solution which enhances the antimicrobial and biofilm-resistant efficacy of the surface, and which prevents a loss of the antimicrobial properties of the surface which may occur over time. Preferably, the enhancement agent is citrate ion and the cationic polyelectrolyte is poly(diallyldimethylammonium chloride), also known as poly-DADMAC. The system is particularly beneficial for surfaces of articles such as contact lenses.Type: ApplicationFiled: November 13, 2008Publication date: October 7, 2010Applicant: QUICK-MED TECHNOLOGIES, INC.Inventors: Susan Leander, William Toreki, Gerald Olderman, Albina Mikhaylova
