Abstract:
1. A fluid container for containing a liquid nutrient having a pH equal to or greater than about 2.5, said container having an interior surface comprising a metal-ion sequestering agent immobilized therein for removing a designated metal ion from said liquid nutrient for inhibiting growth of microbes in said liquid nutrient and an antimicrobial agent for reducing and/or maintaining the amount of microbes in said liquid nutrient to a prescribed condition, wherein said metal-ion sequestering agent comprises derivatized nanoparticles comprising inorganic nanoparticles having an attached metal-ion 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), and wherein said metal ion sequestering agent is attached to the nanoparticle by reacting the nanoparticle with a silicon alkoxide intermediate of the sequestrant having the general formula: wherein x is an integer from 1 to 3; R is an alkyl group; and R′ is an organic group containing an alpha amino carboxylate, a hydroxamate, or a catechol.
