| 摘要 |
The present invention relates to antimicrobial agents, methods for the production of these agents, and the use of these agents. The antimicrobial agent of the present invention includes a water-soluble polymer and oligodynamic metal ions which interact with counter-ions of the polymer such that the metal ions are bound to corresponding counter-ions. The water-soluble polymer controls a sustained release of the metal ions. The oligodynamic metal ions preferably include small size metal particles (e.g., nano-sized silver particles) that interact to the water-soluble polymer as well as metal ions derived from one or more water-soluble oligodynamic metal compositions (e.g., metal sulfates and/or metal nitrates). The agent may also include one or more acids, including organic acids (such as sulfates, carboxylic acids, amines, hydroxyls, nitrates, and phosphates) and/or non-organic acids (such as boric acid and dioctylborate).
