Ball milling enhances the antiviral activity of inexpensive inorganic materials

Since the COVID-19 pandemic, developing surfaces that can inactivate viruses upon contact has become an important goal in public health care. Ideally, such surfaces would work on their own without requiring chemical disinfectants, so they could offer consistent protection in hospitals, public transportation and other shared spaces. This has driven scientists worldwide to search for durable antiviral materials that can be used in everyday surfaces.
