Sintx Technologies publishes study of antiviral activity of Silicon Nitride

SINTX Technologies (SINT) announced the publication of a peer-reviewed study demonstrating that silicon nitride exhibits potent antiviral activity against multiple infectious virus strains, including SARS-CoV-2 and MERS-CoV. The study, conducted in collaboration with Professor Kylene Kehn-Hall’s group at Virginia Polytechnic Institute and State University, further strengthens the evidence for using silicon nitride in a wide range of infection-control applications. The study demonstrated that direct contact to alpha-phase silicon nitride reduced infectious SARS-CoV-2 titers by up to 99.97% within 10 minutes and complete inactivation observed by 30 minutes. In addition, 97% inactivation with contact to Si3N4 when embedded in textile fabric widely used in a variety of medical devices and PPE products. The material also demonstrated similar broad-spectrum virucidal activity against several SARS-CoV-2 variants and MERS-CoV, with minimal cytotoxicity in mammalian cell cultures.
