The U.S. Environmental Protection Agency (EPA) approved NANOSHIELD (EPA number 84542-9), a self-disinfecting, antimicrobial transparent film. Nanoshield uses a patented form of copper to continuously keep high-touch surfaces free of viruses and bacteria, which reduces the transmission of infectious diseases, like COVID-19, via common surfaces.

EPA approval comes after Nestlé Professional announced deploying Nanoshield screen protectors on its out-of-home coffee machines. As public health orders for the COVID-19 pandemic expire in the US, facilities everywhere will look for proven solutions to keep patients, students, customers and employees protected from a spike in coronavirus cases or other common viruses. Nanoshield’s continuous activity defends against viruses and bacteria to provide a practical and cost-saving solution between scheduled cleanings. Nanoshield is available in rolls or tape, and the film can be sized and customized for a variety of applications.

Nanoshield Kills Faster

In tests conducted in labs around the world, Nanoshield killed viruses ranging from those that cause the common cold to staph infections in hospitals.

99.99% of Coronavirus SARS-CoV-2 (COVID-19) in 15 minutes

99.99% Staphylococcus aureus in 15 minutes

99.99% Influenza (H3N2) in 3 minutes

99.95% of Coronavirus 229E in 15 minutes

99.95% of Coronavirus 229E in 15 minutes

99.99% E. coli in 5 minutes

99.95% of Coronavirus 229E in 15 minutes

99.89% Escherichia virus (MS2) in 5 minutes

Why Nanoshield

Continuous Self-disinfecting Power

Nanoshield is continuously disinfecting: within seconds viruses and bacteria begin being eliminated, and within minutes their numbers reach undetectable levels. Unlike traditional disinfectants where viruses and bacteria can thrive in between sanitation procedures, Nanoshield is constantly fighting a war against these unwanted germs on your behalf. Applying Nanoshield film can reduce the transmission of infectious diseases via common surfaces.

Antimicrobial Technology

Microbes, or microorganisms are tiny living things too small to see with the naked eye, such as viruses and bacteria.

Nanoshield is a range of antimicrobial films that eliminate both viruses (antiviral) and bacteria (antibacterial). Turn any surface or device into a death sentence for microbes.

Patented Copper Compound

Not all metals have equal antimicrobial performance. Copper has a unique electron structure that easily takes part in oxidation-reduction reactions; silver and gold do not so they are less reactive.

Nanoshield isn’t just standard copper. The oxidation state of copper can have a significant difference in antiviral activity. Nanoshield contains a patented copper compound which makes us the fastest at eliminating viruses and bacteria

How Nanoshield Works

Copper Ions

Nanoshield is a protective film which produces electrically charged copper ions. They attach to viruses and bacteria, altering their structure and stopping the way they work.


Nanoshield reacts with molecules produced by bacteria (H₂O₂, O₂ •–) to form a chemical substance called Reactive Oxygen Species (ROS). ROS damages both the proteins and nucleic acids in viruses and bacteria, providing an antibacterial and antiviral effect.

Direct Contact

All viruses are surrounded by a protective protein layer that holds the infectious components inside. In order for viruses to spread, this layer needs to remain intact. Nanoshield copper particles are rapidly absorbed into this protein layer, bursting their protective wall.

What is Nanoshield?
Nanoshield is a self-disinfecting antimicrobial film, made by the world leader in its product class. Nanoshield has been applied to touch points and surfaces around the world. Our film uses a patented form copper with excellent antiviral activity to continuously keep surfaces free of viruses and bacteria.
Does Nanoshield kill 99.99% of bacteria and viruses?
Yes. All Nanoshield products are manufactured using the same patented antimicrobial agent. We have tested numerous viruses and bacteria to ISO 21702 (antiviral) and ISO 22196 (antibacterial). To request specific lab reports, please contact us.
Is Nanoshield effective against COVID-19?
Yes. During tests, Nanoshield showed a log4 (99.99%) reduction of the SARS-CoV-2 virus (COVID-19) within 15 minutes of contact.
