Scientists have discovered a 'toy' — ok, it's a molecule called evACE2, which could be used in a nasal spray.
The virus (via its spike protein) will grab the toy (i.e. evACE2) instead of the ACE2 receptor on the surface of the cell, and once having grabbed the toy, the virus then either floats harmlessly around or is being cleared by a macrophage immune cell. It either case, the virus can no longer cause infection!
Wow, just wow, science is awesome!
The scientists have formed a startup company, Exomira, to take the patent, and mass produce the 'toy' (evACE2).
