What challenges need to be overcome to make DNA chips more applicable as storage media

(Nanowerk News) The hereditary molecule DNA can store a great deal of information over long periods of time in a very small space. For a good ten years, scientists have therefore been pursuing the goal of developing DNA chips for computer technology, for example for the long-term archiving of data. Such chips would be superior to conventional silicon-based chips in terms of storage density, longevity, and sustainability. Four recurring basic building blocks are found in a DNA strand. A specific sequence of these blocks can be used to encode information, just as…
