Human Coronavirus 229E Is Still Infectious on Normal Touching Surface

The evolution of new viruses from animal respiratory tracts and re-emergence of historically virulent strains poses a major threat to human health. The transmission of zoonotic virus strains from person to person is inefficient, and may limit the spread of transmission at the beginning, but it may be infected by contact with contaminated surfaces. Enveloped viruses are usually susceptible to environmental pressures, but the human coronaviruses that cause severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) have recently raised concerns about contact transmission during outbreaks....

Comparison of Nano Metal Antibacterial Technologies

Using Functional Nano Metal As A More Effective Antibacterial Material.

Nano metal antibacterial materials have always been leading the research and development direction of antibacterial materials. Traditional antibacterial methods tend to use vapor deposition, sol-gel process, hydrothermal synthesis, precipitation and redox methods in the production of Nano metals. The latest production technique tends to sputter using Nano metals. Regardless of whichever method is used, the advantage of the metal particles is that these particles are distributed in a high proportion on the surface of the material, so that the antibacterial results of the Nano metal can be effectively exerted.

Principle and Design of ACTife Virus Inactivation Function

Traditional Metal Ion Antibacterial Technology

The report that the copper surface can be used for virus inactivation is no longer news. A research reported from Myant Inc. in Ontario, Canada pointed out that a series of redox reactions triggered by monovalent copper Cu+ and divalent copper Cu++ on the copper surface, including the production of reactive oxygen species (ROS) on the metal surface, and the generation of OH- (hydroxyl free radicals), which is highly toxic to the virus, will cause the destruction of the virus genome and at the same time disintegration of the envelope and the drop of surface spurs....
