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.
