Combining Randomness and a High-Capacity DNA Memory

In molecular computing, it has long been a central focus to realize robust computational processes by suppressing the randomness of molecular reactions. To this end, several methods have been developed to control hybridization reactions of DNA molecules by optimizing DNA sequences and reaction parameters. However, another direction in the field is to take advantage of molecular randomness rather than avoid it. In this paper, we show that randomness can be useful in combination with a huge-capacity molecular memory, and demonstrate its application to an existing technology -- DNA ink.
