According to Global Times, the new weapon is not a drug or a compound but some nanomaterial.
"Chinese scientists have developed a new weapon to combat the #coronavirus," the news portal tweeted on Sunday.
"They say they have found a nanomaterial that can absorb and deactivate the virus with 96.5-99.9 per cent efficiency," it added.
Nanomaterials are used in a variety of manufacturing processes, products and healthcare including paints, filters, insulation and lubricant additives.
In healthcare, Nanozymes are nanomaterials with enzyme-like characteristics.
According to the US NIH, scientists have not unanimously settled on a precise definition of nanomaterials, but agree that they are partially characterized by their tiny size, measured in nanometers.
"Nanotechnology can be used to design pharmaceuticals that can target specific organs or cells in the body such as cancer cells, and enhance the effectiveness of therapy," said NIH.
However, while engineered nanomaterials provide great benefits, "we know very little about the potential effects on human health and the environment. Even well-known materials, such as silver for example, may pose a hazard when engineered to nano size," according to NIH.
