Abstract: The present invention comprises antimicrobial articles for use with a percutaneous device, comprising a matrix which may contact the percutaneous device in a three-dimensional mode and release antimicrobial agents (e.g., silver ions) to the percutaneous device access site. In addition, the antimicrobial article of the present invention may donate moisture to a dry dermal site (e.g., a dry wound bed) and/or absorb liquid or exudates of a dermal site. The present invention also comprises methods for treating and/or preventing an infection using the antimicrobial articles of the present invention.

Abstract: The present invention comprises compositions and methods for providing antimicrobial compositions. The antimicrobial compositions comprise gel delivery vehicles comprising stabilized silver, wherein ionic silver is provided to a site for antimicrobial purposes. Methods of making and using such compositions are taught, including application of the silver-containing gel compositions to wounds, burns, abrasions, cuts, surgical incision, sites where skin or organ integrity has been breached, and other sites to supply an antimicrobial environment.

Abstract: The present invention comprises methods and compositions comprising metal nanoparticles. The invention comprises metal nanoparticles and surfaces treated with a metal nanoparticle coating. The present invention further comprises compositions for preparing nanoparticles comprising at least one stabilizing agent, one or more metal compounds, at least one reducing agent and a solvent. In one aspect, the stabilizing agent comprises a surfactant or a polymer. The polymer may comprise polymers such as polyacrylamides, polyurethanes, and polyamides. In one aspect, the metal compound comprises a salt comprising a metal cation and an anion. The anion may comprise saccharinate derivatives, long chain fatty acids, and alkyl dicarboxylates.
