Abstract:
1. An article for inhibiting the growth of a microbes in a liquid nutrient when placed in contact with the liquid nutrient, said article having a polymeric layer thereon, said polymeric layer having a sequestering agent such that when said article is placed in contact with said liquid nutrient said sequestering agent inhibits the growth of microbes in said liquid nutrient, said sequestering agent comprises derivatized nanoparticles comprising inorganic nanoparticles having an attached sequestrant, wherein said inorganic nanoparticles have an average particle size of less than 200 nm and the derivatized nanoparticles have a stability constant greater than 10 10 with iron (III), said sequestering agent is immobilized in said polymeric layer and comprises 0.1 to 50.0% by weight of the polymeric layer, and the polymeric layer contacts the liquid nutrient and is permeable to water.
