Enzyme transistor circuits

摘要

The authors explore the possibility of constructing extremelynhigh-density computing architectures using molecular electronicsntechnology. By employing the of biological new molecules, such asnenzymes, new integrated circuit architectures which are essentially freenfrom interconnection problems could be constructed. To clarify thenproposed concept, the authors present a functional model of a basicnbiomolecular switching device called an `enzyme transistor'. The enzymentransistor is, in a sense, an artificial catalyst which selects anspecific substrate molecule and transforms it into a specific product.nUsing this primitive function, various wire-free computing circuits cannbe realised: examples include biochemical amplifiers for analogue signalnprocessing and basic digital circuits. Addressing the implementationnissue, the authors also propose bioelectronic implementation of enzymentransistors
