In this work, a simple and universal platform was developed for the integration of multiple logic gates to achieve resettable half adder and half subtractor functions based on the characteristics of magnetic beads and DNA. The signal reporter was composed of a split G-quadruplex DNAzyme and AuNP-surface immobilized molecular beacon molecule.
