There was a paper a year or so ago in Science.

NP complete problems are tough for computers, but can be modelled by a
set of DNA sequences and reactions that explore all possibilities.

This gave rapid solutions to some problems, but could involve inpossibly
large quantities of DNA (several tons :-) for larger problems.
