Abstract

A polyoxometalate hosting Ag⁺, [AgP₅W₃₀O₁₁₀]¹⁴⁻, has been studied for its sustained and controlled release of Ag⁺ triggered by Na⁺ replacement at room temperature for long-lasting bacteriostasis, whose antibacterial activity is not eliminated after repeated exposure tests because of the protection of Ag⁺ by the polyoxometalate skeleton.
