What is it about?

DNA circuits employing DNA strand displacement technique are considered as a possible replacement for silicon-based circuits, especially in implantable medical devices, because of its compatibility with bio-signals, smaller size, and light weight. In this work, a new DNA strand displacement based, three-input spatially localised majority gate using DNA hairpins is proposed. The DNA hairpins used in this majority gate are tethered to an Origami substrate, and hence, the DNA hairpins are spatially separated from each other. The localisation helps the designer to reuse the strands, without causing any spurious reactions. It is believed currently that no design is available in the literature for a localised DNA majority gate. The visual DSD software is used for simulating the proposed majority gate.
