In the era of "big data" finding solutions for data storage alternative to those based on silicon or magnetic tapes is an urgent need for our society. The development of polymers that can store information at the molecular level has opened up new opportunities for ultrahigh density data storage, long-term archival, anti-counterfeiting systems and molecular cryptography. Biological pores of bacterial origin hold the promise to accurately decode the digital information encoded in tailored-made polymers opening up promising possibilities to develop writing-reading technologies to process digital data using a biological-inspired platform.
