Abstract
Herein, we developed a reliable and portable biosensor (TDR-PGM nanomachine) for the sensitive detection of microRNA by integrating an efficient toehold-mediated strand displacement reaction module (TDR) and a personal glucose meter (PGM). The system provides a versatile methodology for microRNA detection in real samples and holds broad prospects in point-of-care diagnosis.
