A Test of Antifungal Spray Formulation Containing Nanosized Silica-Silver Particles Prepared by Using Gamma Irradiation for Practical Use to Control Indoor Fungi

The present study described an antimicrobial spray composition comprising nanosized silica-silver particles, in which nano-silver is bound to silica molecules and a water-soluble polymer, the nanosized silica-silver particles prepared by irradiating a solution comprising a silver salt, silicate and the water-soluble polymer with radiation rays. According to a surfactant addition, the compositions were not turbid and were colorless. Also samples (cotton fabrics and wallpaper) were treated with the compositions also did not cause any stains even after drying under sunshine and at $80^{\circ}C$. Our results suggested that the spray formulation product was of practical use to control indoor fungi.
