Deoxyribozyme-Based Half-Adder
Abstract
We have constructed a solution-phase array of three deoxyribozyme-based logic gates that behaves as a half-adder. Two deoxyribozymes mimic i(1)ANDNOTi(2) and i(2)ANDNOTi(1) gates that cleave a fluorogenic substrate, reporting through an increase in fluorescence emission at 570 nm. The third deoxyribozyme mimics an i(1)ANDi(2) gate and cleaves the other fluorogenic substrate, reporting through an increase in fluorescence emission at 520 nm. Together, this system represents the first example of a decision-making enzymatic network with two inputs and two outputs. Similar systems could be applied to control autonomous therapeutic and diagnostic devices.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
