    摘要: The development of the first solution-phase molecular assembly comprising over 100 molecular logic gates, which more than quadruples the complexity performed by any previous system. “MAYA-II” is a second generation molecular automaton capable of playing a complete game of tic-tac-toe against a human opponent, and encompasses 76 permissible game plays. MAYA-II is more user-friendly than MAYA-I, as it signals both players move in a two-color output system and imposes no constraints on the position of the human player's first move. MAYA-II is constructed from three classes of stem-loop controlled deoxyribozyme-based logic gates that are allosterically modulated by input oligonucleotides to produce fluorescent output signals.

    摘要: Complex of an anti-cocaine aptamer and the dye diethylthiotricarbocyanine behaves as a calorimetric sensor with attenuation in absorbance at 760 nm for cocaine in the concentration range of 2-5000 μM. Mechanistic studies indicate an intermolecular displacement of the dye as the mechanism of action of the sensor. As the dye is insoluble in buffer, cocaine binding can be detected as displaced dye precipitates and supernatant decolorizes.

    摘要: Provided herein are molecular automaton systems for identification, isolation, or elimination of a target biological object. Some embodiments include modules specific for a target biological object having a first biological object surface marker and a second biological object surface marker. Some embodiments include modules specific for a target biological object having a first biological object surface marker but not a second biological object surface marker.
