The Counting Machine as a Modular Nanoscale DNA Component.

A major goal in nanotechnology is the find useful forms of DNA computation. This broad definition includes amplifiers, logic gates, oscillators, structural manipulations, and many more forms of controlled responses. We believe an enzyme-free, DNA toehold exchange catalyzed system that preforms the computation of “counting” can be useful in various fields of biotechnology. Counting, by our definition, relies on two main principles. The first is the input that is being counted must be the same with each pulse and the second is the output of the counter must be independent of the input quantity or concentration. That is, regardless of the amount of input used, the counter must only reach completion after the specified number of counts, or pulses.
