Researchers at RMIT University have developed a lightweight, flexible acrylic film coated with nanoscale pillars that can rupture viruses on contact, specifically targeting human parainfluenza virus type 3 (hPIV-3). This new material offers a sustainable alternative to traditional disinfectants, potentially reducing the spread of infections in everyday environments.
- 01The new acrylic film can destroy up to 94% of hPIV-3 virus particles within an hour of contact.
- 02The material features thousands of tiny pillars that mechanically rupture viruses, offering a chemical-free solution.
- 03This innovation addresses the limitations of traditional disinfectants, which can harm the environment and contribute to antimicrobial resistance.
- 04The film's design is scalable, allowing for widespread industrial applications in healthcare, food packaging, and public transport.
- 05Further research is needed to explore the long-term durability and effectiveness of these nanotextured surfaces.

Researchers at RMIT University have created a groundbreaking acrylic film coated with nanoscale pillars that can effectively destroy viruses on contact. This innovative material targets the human parainfluenza virus type 3 (hPIV-3), with lab tests showing that up to 94% of virus particles were ruptured within an hour of contact. Unlike traditional disinfectants, which rely on chemical agents that can harm the environment and contribute to antimicrobial resistance, this film employs mechanical force to rupture viruses, providing a sustainable alternative. The film's design is lightweight, flexible, and cost-effective, making it suitable for a wide range of applications, from hospital equipment to public transport systems. The research highlights the importance of surface topography in preventing the spread of infections and suggests that tightly packed nanopillars, spaced about 60 nanometers apart, are most effective. While the film shows promise, further studies are necessary to assess its long-term durability and effectiveness in real-world settings.
