- ... DNA nanodevices that mimic natural biomolecular machines changing configurations in response to external inputs have enabled smart sensors to live cell imaging. We report for the first time the development of a dynamic DNA nanomachine that is anchored on a cell’s surface and undergoes pH-responsive triplex–duplex conformation switching, allowing tunable sensing and imaging of extracellular pH.
