The leftmost is a solvent in which graphene oxide material is dispersed. The white dots are the coronavirus, which disappears as you move to the right.
COVID-19: Fight off viruses with graphene oxide:
Kumamoto University:
Industrial Nanomaterials Research Institute:
It was confirmed that the new coronavirus can be almost completely removed with graphene oxide.
Graphene oxide nanosheets:
“Fine material called graphene oxide nanosheet” is used.
Experiments with dispersed solvents removed the new coronavirus almost completely.
In the experiment:
Thickness: 1 nanometer-several nanometers,
Size: 0.1 micrometer square,
A “solvent in which a sheet-shaped graphene oxide material was dispersed” was used.
Complete removal of virus in 1 hour:
Place the solvent on the medium of the new coronavirus.
In the experiment, the virus could be almost completely removed in about 1 hour.
The experiment was conducted in the laboratory for the new coronavirus at Kumamoto University.
Industrial Nanomaterials Research Institute:
We are conducting life and medical research on highly functional nanosheet materials such as graphene oxide.
This study:
This is a joint research group of Professor Hayami and Associate Professor Ikeda of Kumamoto University.
Field of use:
Graphene oxide itself can be inexpensively produced from a material obtained by oxidizing graphite.
It has also been confirmed that there is no cytotoxicity to humans.
“It’s also reproducible,” says Professor Hayami.
The dispersion solution of graphene oxide nanosheets can be mixed with polyethylene non-woven fabric.
Professor Hayami:
He said that he is considering “commercialization of masks using non-woven fabrics and filters for air conditioners” in collaboration with industry.
The research paper will be submitted to a British scientific journal.
