Rewritable liquid computing with sequential DNA origami registers is faster and more compact than today’s silicon-based versions

"placed DNA origami register onto  solid glass 2D surface... output oligonucleotide floating in liquid from specific logic gate attaches to glass-mounted register... after output read/ logic gate instructions determined, it detached, resetting register for rewriting... amplifier boosted output so gates, oligonucleotides, registers find one another easily... all takes place in single tube within 90 minutes... large-scale DNA computing circuits, visual debugging, automated execution of DNA molecular algorithms, massive storage"
