Multiply Configurable Optical‐Logic Systems Based on Cationic Conjugated Polymer/DNA Assemblies

Information processing by integrated logic gates capable of YES, NOT, AND, NAND, INH, and INHIBIT operations can be simulated using fluorescence resonance energy transfer (FRET) in cationic conjugated polymer/DNA/ ethidium bromide (EB) intercalating-dye assemblies. Additionally, a reversible XNOR logic gate can be designed and implemented with these materials. The figure shows the scheme for the INHIBIT logic gate.
