One interesting thought came to me when I was thinking about
the way to fight viruses. Since the virus basically destroys
itself when it attaches to the cell membrane and injects its
RNA/DNA, would that be a way to fight viruses? Say, you create a
dummy cell, or just a membrane tisue, and lure the virus to it.
Then, virus attaches to it and injects its genetic material
into the environment that does not contain any polymerase,
thus, effectively destroying itself without giving "birth" to its
clones. The question comes about other viruses that manage
to enter living/working cells and multiply in there. To
fight that, you simply have to overwhelm the environment
with dummy cells or luring membrane tissues, and immune
system will do the rest of the job. This way you can
fight any virus, basically, even HIV, without worrying
about virus being mutated.
