GO has been studied quite often for bio-medical nanotechnology use. Nanotechnology has been studied for use in corona viruses . Applications to explore include ability to act both within and outside the cells.
This study was to see how effective it is against the RONA. Testing included the spike - open and closed, the ACE2 receptor, as well as the Bound ACE2 receptor. It reacts with all 3. But less with the bound ACE2.
The impact of GO on 4 different infectious virus were studied. Thin, biological‐grade GO nanoscale sheets are able to significantly reduce copies for three different viral clades. I’m not sure which was the 4th viral clade for which it wasn’t effective.
More study is proposed:
GO nanosheets are proposed to be further explored as a nanoscale platform for development of antiviral strategies against COVID‐19.
“Testing included the spike - open and closed, the ACE2 receptor...”
No. That was only running some computer simulations in a docking program using coordinates from different crystal structures.
Awessome thanks!
