We have proposed “nanofabrication process by protein supramolecules”, which was named “Bio Nano Process” (BNP)1,2). In the BNP, protein supramolecules work as templates for the biomineralization of homogenous nanoparticles/nanowires, which are semiconductor and metal-complex materials. The surfaces of protein supramolecule are chemically or genetically modified and let self-organize into functional nano-structures. We have already designed and produced several kinds of protein supramolecules for the BNP and applied them to produce key components of nanodevices, such as a floating nanodot gate memory (FNGM), a single electron transistor, a Re-RAM, quantum solar cell, bio-sensors, Single Nucleotide Polymorphism (SNP) sensing LoC, dyes-sensitized solar cell, thermo-electronic device, and other electronic devices 2,3,4).
