Prevents the spread of infection by bacteria and viruses

About the experimental results using the GUD sheet

Through joint research with Gunma UniversityNew Coronavirus (SARS-CoV-2)And fungi (Escherichia coli and Staphylococcus aureus),
We conducted experiments with viruses (T4 phage and Mu phage) and confirmed that they have sterilization and virus inactivation performance.

Practical example as infection prevention

GUDMoreWe handle buttons and handle covers and masks that use sheets.

GUD mask

Copper mask
Size: Length 8cm x Width 15.5cm Contents: 1 sheet (Maximum height when unfolded: 12cm)
The GUD mask is a copper mask that uses a copper fiber sheet that has sterilization and virus inactivation performance, and is an overmask that can be worn on top of the mask.

By wearing a GUD mask
① Eliminates and inactivates bacteria and viruses attached to the GUD mask.
(XNUMX) Prevents infectious bacteria and viruses from adhering "from mask to hand" and "from hand to mask" when the mask is moved by hand.






GUD sheet (sealed) button seal

Size: Circular with a diameter of 26 mm Contents: 10 sheets
A button cover processed from a copper fiber sheet (GUD sheet) that has sterilization and virus inactivation performance.

It is used by pasting it on the buttons and touching parts that are used on a daily basis.
Attaching a button sheet will help prevent the spread of infection by bacteria and viruses on your hands.

The double-sided tape used for the button cover is an "environmentally and human-friendly" tape that does not easily generate VOCs (volatile organic compounds).


                                                     

GUD sheet (seal processed 20 x 24 cm)

Size: Length 20 cm x Width 24 cm Contents: 1 sheet (double-sided sticker processed)
A copper fiber sheet with a length of 20 cm and a width of 24 cm that has sterilization and virus inactivation performance.

This product uses "environmentally and human-friendly" tape that does not easily generate VOCs (volatile organic compounds) so that it can be attached to things that touch the hands such as handles and buttons.

The GUD sheet itself is flexible, making it easy to cut and paste.
Cut it to the size you like and stick it on a place that you often touch.




What is a photocatalyst in the first place?

A photocatalyst, when irradiated with ultraviolet light or visible light, generates hydroxyl radicals that have an oxidizing effect and substances called active oxygen, and decomposes and inactivates organic substances (including bacteria and viruses).
At Gunma University Itabashi Laboratory, we are researching visible light-responsive photocatalysts that show catalytic reactions even with visible light, which has less energy than ultraviolet rays, and are incorporating them into our products.

About the relationship between copper and the new coronavirus

Researchers in the United States have confirmed that the survival time of the new coronavirus attached to copper alone is overwhelmingly shorter than that of other everyday substances.
