Why would you store digital information in DNA?
summary
Claim: DNA can be read, written and made archival by chemistry, not just biology. Tools: enzymatic PCR amplification, high-throughput sequencing, chip or light/electrochemical/inkjet synthesis of 200-base oligos, and glass-encapsulated nanoparticles that prevent decay. Results: error rates (∼2% substitutions, ∼6% indels) are handled by outer/inner error‑correction; PCR enables massive copy‑out; particles hold ~10,000 bits each so millions of bits fit where a DVD holds ~160; accelerated aging predicts a 1000‑year half‑life (≈500+ years readable). Applied: product barcodes survive textile processing and have been commercialized; megabyte‑scale demos (music, newspaper, video) succeed but write cost remains high.
