Plasma jet is found to kill coronavirus on six different surfaces like cardboard and leather in as little as 30 SECONDS
- Scientists have discovered that a plasma jet can effectively kill the coronavirus
- They made a device that uses argon to power plasma through the system
- Plastic, leather, cardboard, metal, a basketball and a soccer ball were used in the test
- Metal took 30 seconds and plastic and leather football took 30-60 seconds
- Cardboard and basketball took up to 60 seconds to be virus free
Scientists are working tirelessly to develop effective weapons against the coronavirus, and a team from the University of California has discovered that plasma may be our saving grace.
The group showed that cold atmospheric plasma fueled with argon was able to kill the new coronavirus in as little as 30 seconds.
The device, manufactured with a 3D printer, is composed of electrodes, a chamber that contains the argon feed gas and a high voltage power source.
It was able to remove the virus from six different surfaces, ranging from plastic to leather – and the team is hoping to create a compact version for the public.

Richard E. Wirz, author of the study, said: “This is just the start”.
“We are very confident and have very high expectations for plasma in future work. In the future, many answers for the scientific community will come from plasma ”.
The study looked at treatment with cold atmospheric plasma fed with argon on surfaces infected with the virus.
This included the plastic, metal, cardboard, and leather of basketball, football, and baseball.

The team found that the metal was quickly decontaminated in just 30 seconds, and the plastic and leather soccer ball took about 30 to 60 seconds.
The last two surfaces, the cardboard and the basketball, exhibited effective inactivation of the virus after 60 seconds of treatment.
And further testing showed similar results with cotton fabric used in face masks.
“ Plasma is one of the four basic states of matter and can be created by heating a neutral gas or subjecting it to a strong electromagnetic field, the team shared in a statement.
“A relatively new technology, cold atmospheric plasma is an ionized, near room temperature gas that has been shown to be effective in cancer treatments, wound healing, dentistry and other medical applications.
A second experiment was conducted, but this time the team used helium-fueled plasma.
However, this method was not as effective – even with treatments lasting up to five minutes.
The team suggests that this is due to lower levels of reactive oxygen and reactive nitrogen when using gas powered by helium, compared to argon.

Zhitong Chen said the researchers were building a compact device that could be widely used to treat surfaces of the coronavirus with plasma.
He also notes that using plasma is a safer and healthier option than chemicals or other treatments.
“Everything we use comes from the air,” Chen said.
“Air and electricity: it’s a very healthy treatment with no side effects.”
The team hopes that this system will one day be accessible to the public around the world.
