Exploiting Dark Fluorophore States to Implement Resonance Energy Transfer Pre-Charge Logic

As lithographic feature sizes approach fundamental scaling limits, a variety of computational domains remain incompatible with integrated circuits merely due to their operating principles. Resonance energy transfer (RET) logic offers a molecular-scale solution for accessing these untapped domains. This emerging technology uses self-assembled networks of fluorescent molecules to perform computation at scales far below the diffraction limit and in environments that preclude silicon electronics. In this article, the authors propose a new form of RET logic design that yields a library of nonlinear logic gates that can be cascaded to build more complex integrated molecular circuits.
