When you think in terms of (fundamental) strings you should certainly also
think in terms of (D-)branes instead of "plates". The Casimir effect between
branes has been studied.
You might want to try to look at some of the following papers:
A recent one for instance is
Shoichi Ichinose, Akihiro Murayama:
Casimir Effect in the Brane World
http://arxiv.org/abs/http://www.arxiv.org/abs/hep-th/0401015
but I am not sure about the results here.
A more classical one is probably
Michal Fabinger, Petr Horava:
Casimir Effect Between World-Branes in Heterotic M-Theory
http://arxiv.org/abs/http://www.arxiv.org/abs/hep-th/0002073 .
