Oxynitride bioceramics for safer and long-term virus inactivation

Important results from the project

The aiming nitride powders were oxidised, characterised and their antiviral properties were tested against copper, an established antiviral agent. The results indicated that oxidised nitride ceramics were highly effective in binding and inactivating SARS-CoV-2, adenovirus, H1N1, and Norovirus after from one minute to hours of contact. The in-situ testing in the animal hospital has not shown a clear difference before the targeting materials and the control, but bacteria. One reason could be no enough virus in the places where we placed.

Approach and implementation

The material preparation and characterization and the production of the aiming sanitizer have been done in MiM group (UU). The formulation based the oxidization and hydrophilicity has been optimized. The virus group in UU together with MiM have made the testing of virus inactivation for the materials, and samples collected from the animal hospital (SLU). The group in the animal hospital has made a plan and placed the aiming materials and controls in proper places and collected samples for antivirus testing.
