Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Major challenges in molecular electronics include miniaturization, and the realization of a simple function to alter silicon‐based electronics. It has been hard to develop a single molecular‐based computing system, since such systems need complex functionality to be developed at the single‐molecular level. To develop a molecular‐based biocomputing system, a bioprocessing device is demonstrated that consists of recombinant azurin/DNA/inorganic material hybrid to perform the various functions in a device. A metalloprotein which exhibits redox behavior is used as a biomemory source. The redox property could be controlled with command materials (conducting nanoparticles, heavy metal ions, and semiconducting nanoparticles) to perform 'information reinforcement, ' 'information regulation, ' and 'information amplification' functions, respectively. This bioprocessing device could be a foundation to develop single‐biomolecular‐based computing systems.</p> </abstract>
