Um, title: the spikes take out 96% of virus particles that come into contact with them. So the next problem is: how do you make virus particles come into contact with this surface? If you wait for them to fall onto it, you could be waiting a very long time. Also, the virus has to be sitting on the spikes for several hours. This is very interesting work, but there's a lot to be done before there are practical applications, no?
