Biological Logic Gates: DNA Computing in Action

DNA nanobots function as biological logic gates, processing information within the body much like computers process data. By detecting combinations of cellular signals—such as the presence of specific proteins or environmental factors—they make complex decisions about when and where to act. For example, a nanobot might only release its therapeutic cargo if multiple cancer markers are present, ensuring precise targeting. As detailed in this Nature article, such molecular logic enables powerful, context-aware responses inside living tissues.
