可重构的DNA纳米结构可以被设计为响应外部刺激,如核酸,pH,小分子和酶。在这项研究中,我们在DNA链中引入了可光裂解的连接体,这些连接体引发了二元DNA纳米开关的构象变化。我们演示了使用紫外光控制输出,在生物传感和分子计算中具有潜在的应用。
Reconfigurable DNA nanostructures can be designed to respond to external stimuli such as nucleic acids, pH, small molecules and enzymes. In this study, we incorporated photocleavable linkers in DNA strands that trigger a conformational change in binary DNA nanoswitches. We demonstrate control of the output using UV light, with potential applications in biosensing and molecular computation.
