The chip's surface holds 64 synthesis sites, each ringed by tiny electrodes that lower the local pH on demand to trigger enzymatic growth of a specific DNA strand.\\n\\nThe device made 64 distinct sequences of 39 nucleotides each in parallel, roughly five times more than the ~12 sequences prior enzymatic chips could handle at once. As a proof of concept, the team encoded a 169-byte text message into the synthesized DNA, demonstrating a path toward portable, environmentally friendlier DNA data storage.\\n\\nLed by Harvard SEAS professor Donhee Ham with co-first authors Woo-Bin Jung and Han Sae Jung, the work involved the Broad Institute, DNA Script and POSTECH, and was funded in part by IARPA and Horizon Europe. It was published July 8 in Nature Electronics.\\n\\nSources:\\n- https://www.sciencedaily.com/releases/2026/07/260708022202.htm\\n- https://scitechdaily.com/harvard-scientists-turned-a-silicon-chip-into-a-dna-factory/"}}
