A new DNA nanoprobe based on a Y-shape and pyrene-modified DNA self-assembly is developed to sensitively and specifically detect microRNA through a pyrene excimer–monomer switch. Exhibiting the capability of self-delivery and resistance to nuclease degradation, the nanoprobe has been successfully applied for microRNA imaging in live cells.
