Design of elementary molecular logic gates is the key and the fundamental of performing complicated Boolean calculations. Herein, we report a strategy for constructing a DNA-based OR gate by using the mechanism of sequence recognition and the principle of fluorescence resonance energy transfer (FRET). In this system, the gate is entirely composed of a single strand of DNA (A, B and C) and the inputs are the molecular beacon probes (MB1 and MB2). Changes in fluorescence intensity confirm the realization of the OR logic operation and electrophoresis experiments verify these results. Our successful application of DNA to perform the binary operation represents that DNA can serve as an efficient biomaterial for designing molecular logic gates and devices.
