Would be nice here too. The one thing I was wondering about, would it take out arsenic? or other heavy metal contaminants. That seems to be the big thing now, finding filters that do that job besides viral and bacterial removal.
I also wondered if this charged polymer could be adapted to human blood for instance to attract virals and bacteria and thus lower the load for diseases like HIV and so forth.
If that could do the job, maybe they could design a molecule that would recognize when the polymer is full of viral or bacterials and then change course and head out the kidney or rectum.
