Antiviral and antifungal activities of tin molybdenum solid solution oxide prepared using mechanochemical processing

Abstract

Using SnO and MoO₃ as starting materials, a SnO₂–MoO₂ solid solution (SnMO) was prepared using mechanochemical method. Then its antiviral and antifungal activities were evaluated. The obtained sample was a powder with specific surface area of 5.7 m²/g with a rutile-type crystal structure. The amount of ion elution for SnMO into 1/500NB solution was an order of magnitude lower than that of MoO₃. This powder exhibited high antiviral activity against both bacteriophage Qβ and bacteriophage Φ6, suggesting contributions to antiviral activity by both low pH and eluted ions from the powder. Furthermore, a test based on JIS standards revealed that SnMO possesses high antifungal activity. These findings indicate SnMO as an effective material against widely various microorganisms.
