A Surface-Based Approach to DNA Computation

1998 Journal of Computational Biology  
A simple, surface-based model of computation is described and it is shown how to implement an exhaustive search algorithm for the SAT problem on this model.  ...  A new model of DNA-based computation is presented. The main di erence between this model and that of Adleman is in manipulation of DNA strands that are rst immobilized on a surface.  ...  Their work has led to hopes of a DNA computer that can outperform the fastest realizable super computers at such problems.  ...
