US Patent 11174512 Homopolymer encoded nucleic acid memory

Nucleic acid memory strands encoding digital data using a sequence of homopolymer tracts of repeated nucleotides provides a cheaper and faster alternative to conventional digital DNA storage techniques. The use of homopolymer tracts allows for lower fidelity, high throughput sequencing techniques such as nanopore sequencing to read data encoded in the memory strands. Specialized synthesis techniques allow for synthesis of long memory strands capable of encoding large volumes of data despite the reduced data density afforded by homopolymer tracts as compared to conventional single nucleotide sequences.
