分子自动机是分子的混合物,它们经历精确定义的结构变化,以响应与输入的顺序相互作用。以前研究的基于核酸的自动机包括游戏分子设备(MAYA自动机)和用于分析核酸的有限状态自动机,后者激发了用于分析细胞内RNA种类的电路。在这里,我们描述了基于抗体指导的链置换级联的自动机,这些抗体可以通过使用细胞的表面标记作为输入来分析细胞。成功完成分析的分子自动机的最终输出是在人血细胞内特定淋巴细胞亚群的细胞表面上存在独特的分子标签。
Molecular automata are mixtures of molecules that undergo precisely defined structural changes in response to sequential interactions with inputs. Previously studied nucleic acid-based-automata include game-playing molecular devices (MAYA automata) and finite-state automata for analysis of nucleic acids with the latter inspiring circuits for the analysis of RNA species inside cells. Here, we describe automata based on strand-displacement cascades directed by antibodies that can analyze cells by using their surface markers as inputs. The final output of a molecular automaton that successfully completes its analysis is the presence of a unique molecular tag on the cell surface of a specific subpopulation of lymphocytes within human blood cells.
