Progress toward demonstration of a surface based DNA computation: a one word approach to solve a model satisfiability problem.
A multi-base encoding strategy is used in a one word approach to surface-based DNA computation. In this designed DNA model system, a set of 16 oligonucleotides, each a 16mer, is used with the format 5'-FFFFvvvvvvvvFFFF-3' in which 4-8 bits of data are stored in eight central variable ('v') base locations, and the remaining fixed ('F') base locations are used as a word label. The detailed implementations are reported here. In order to achieve perfect discrimination between each oligonucleotide, the efficiency and specificity of hybridization discrimination of the set of 16 oligonucleotides were examined by carrying out the hybridization of each individual fluorescently tagged complement to an array of 16 addressed immobilized oligonucleotides. A series of preliminary hybridization experiments are presented and further studies about hybridization, enzymatic destruction, read out and demonstrations of a SAT problem are forthcoming.
