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

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.
