A semiconductor chip has synthesized 64 unique DNA sequences in water without traditional enzymes, achieving a record-breaking 99.9% accuracy. This breakthrough could slash DNA synthesis costs and turbocharge bioengineering.

The chip synthesized 64-mer DNA strands (64 nucleotides long) with just 0.1% errors

Electrical control replaces expensive enzymes, potentially cutting synthesis costs by 100x

Next-gen chips could scale to thousands of parallel DNA writes for genome-scale engineering

Faster, cheaper DNA writing accelerates vaccine development, CRISPR therapies, and molecular computing

The chip achieved 99.9% synthesis accuracy—equal to premium enzymatic methods but 100x faster and without organic waste.
