Outline of Final Research Achievements

To reduce the risk of infection diseases caused by viruses such as SARS-Cov-2, the antiviral activity of several metal oxides has been evaluated. It was newly found that molybdenum trioxide has highly antiviral activity. Therefore, in this study, aiming for practical use, even more highly antiviral material using molybdenum trioxide was prepared. Specifically,increasing the surface area by adding structure to the coating surface, and making the virus adsorb efficiently on the coating surface were tried. In addition, because of the coronavirus disaster, the antiviral activity of molybdenum trioxide against wild type SARS-Cov-2 was also evaluated and its activity was confirmed.

Academic Significance and Societal Importance of the Research Achievements

新型コロナウイルスによるパンデミックは、およそ3年の期間を費やし、終息を迎えつつある。パンデミックの期間には、感染リスクの低減を目的に、長期間持続する多くの抗ウイルス製品が開発され、上市されてきた。その中で、本研究では、新しく三酸化モリブデンの材料を提案することができ、また、実用化に向けた効率のよい材料についても提案できたことは、意義深いと考えられる。
