In today’s global society, viral infections viral infections have become a serious health challenge, with disease outbreaks able to spread easily and rapidly cross continents. The Coronavirus pandemic has increased the demand for antiviral measures and treatments for clean surfaces, especially in public places.
The team reviewed a range of natural and synthetic surface materials and coatings with documented antiviral properties, including metals, polymers and biopolymers, graphene and antimicrobial peptides, as well as reviewing the physico-chemical properties of surfaces which can influence virus attachment.
The findings also provide an overview of the current practices and applications of antiviral materials and coatings in consumer products, personal protective equipment, healthcare and public settings.
Typically, there is no single solution to prevent the spread of viral infections, and different modes of transmissions adds to the difficulty. The solution often requires a multiple-barrier protection, and next to high hygiene standards and vaccination program, a number of control measures including adequate personal protective equipment (PPE) or antiviral surfaces in public facilities.
The insights, summarized from the published literature, indicate that material science can play a vital role in the development of conceptual and practical measures to slow infectious outbreaks and that both existing and innovative broad-spectrum antiviral strategies should be considered, which could contribute to the challenge and preparedness of future viral pandemics.
NPL is also already working with industry to support new UK based manufacturing of face coverings for healthcare and the general public. NPL experts are also able to provide guidance on meeting relevant standards, and testing of products and materials for both standard and novel design to aid design optimisation.
