Informal Description of the Invention:
A completely molecular computer can be constructed using designed DNA and DNA binding proteins. Several versions of the device are possible. In the simplest device, bacteria or other cells are programmed with DNA sequences and DNA binding proteins that execute logical Boolean operations. It is also possible to construct molecular computers outside cells, but in this case special attention must be paid to providing energy to run the computer. The technology is based on the concept of a molecular flip-flop in which one or more proteins compete for binding to binding sites that overlap. Because only one protein can bind at a time but there are two ways for it to bind, the method can also be used to double the sensitivity of diagnostic assays.
Formal Description of the Invention:
The present invention is a method and apparatus for molecular computing which provides for molecular logic devices analogous to those of electronic computers, such as flip-flops, AND gates, etc. Coupling of the gates allows for molecular computing. The method allows data storage, the transformation of binary information and signal readout. Possible applications include encoding ``read only'' memory for microscopic identifiers, digital control of gene expression, and quantification of analytes. The computing elements also provide means for complex regulation of gene expression.
