Abstract
The present invention relates to antimicrobial compositions including a critical, near critical, or supercritical (densified) fluid and an antimicrobial agent, to methods of forming these compositions, and to methods employing these compositions. An antimicrobial agent can be generated in the presence of a densified fluid, for example, by reacting an oxidizing agent with a precursor to the antimicrobial agent.
