A scientific explanation of copper’s effect on virus and bacteria


Did you know that the Human Coronavirus survives for up to 3-5 days on materials such as stainless steel, glass, ceramic tile, and plastic? In a research published in The New England Journal of Medicine, it was discovered that the survival time of SARS-CoV-2 on copper had a half-life and that the predicted decay time of the virus was very short.

  • Scientist from the US-based National Institute of Allergy and Infectious Diseases Hamilton, MT published in The New England Journal of Medicine the survival time of SARS-CoV-2 at various surfaces.
  • It was found that especially on copper both the half-life as well as the predicted decay was very short.

Antiviral Activity:

  • Human Corona 229E & SARS-CoV-2 virus can survive on surfaces made of materials such as plastic, ceramic tile, glass, and stainless steel for 3-5 days.
  • However, for inactivation time of virus on a Copper surface is 1 hour. This has been tested by the American Society of Microbiology in 2015.


  • “Glycoprotein Spike” has a key role to penetrate & invade the human cell.
  • RNA is critical for replication of the virus.
  • RNA polymerase facilitates the RNA replication as a catalyst.
  • Principle of Antiviral effect of Copper.
  • Antiviral Cu acts as an inhibitor
    of virus RNA replication.
  • Antiviral copper inhibits RNA replication.
  • Transcription: Role of the RNA Polymerase.

On Bacteria

Copper ion infiltrates through the microbial cell-wall
The microbe recognizes the copper ion on the copper surface as essential nutrients. It tries to absorb the nutrients into its cell.
Destruction of cell membrane initiated
The absorbed copper ion penetrates the microbe’s cell membrane. The cell loses its essential nutrients and water.
Acceleration of cell destruction
The copper ion pulls the active oxygen through the penetrated hole in the cell membrane. It causes the cell to decay.
Genome and Plasmid DNA decomposition
The microbe suffers from reduced metabolic activity damages the DNA lead to its complete extinction. Cell replication and self-replication are suspended.
The test purpose was to check the Copper antimicrobial film inhibitory effect against coronavirus.
The test was performed on two Copper antimicrobial films (samples 1 and 2). Our Copper Film is, No.2, and summary of the result:
Efficiency level 4.0 or higher, virus self-disinfectivity is recognized.
  1. Exhibit inhibitory effect against bovine coronavirus.
  2. 4.0 means 99.99% of self-disinfection was observed when the exposure time is more than 4 hr.
  3. Approximately 99.94% of inhibitory efficiency against the virus was detected at 30 minutes.
  4. 99.99% of inhibitory efficiency against the virus was detected at 4 hr.
* Self-disinfectant means that the substance itself has the ability to suppress pathogenic bacteria without the need for disinfectants or disinfection. ** 4.0 means that it has 10,000 times the sterilization power of the coronavirus. (Compared to non-antibacterial treated materials)
