Transducing Complex Biomolecular Interactions By Temperature-Output Artificial Dna Signaling Networks
JOURNAL OF THE AMERICAN CHEMICAL SOCIETY(2020)
摘要
The requirement of special expensive instruments for quantitative information readout has significantly restricted sustainable development, from ideation to execution, of advanced artificial networks. Here we present a step toward a paradigm of evolutionary signaling networks that enable translating complex signaling information into easy-to-read temperature output. Combining DNA molecular engineering with basic optical mechanisms, a DNA/Hemin complex-derived versatile temperature-output transducer is established, which can be coupled with other functional modules to fabricate diverse portable DNA signaling networks by dynamic programming of DNA chemical reactions. Its versatility is successfully demonstrated by constructing self-amplified and logic-circuit-based DNA signaling networks to monitor trace and multibit nucleic acid interactions using a thermometer. This affordable yet powerful DNA signaling network design may portend an era of point-of-care signaling network methodology.
