Phys.org  February 25, 2022 Researchers at Arizona State University have shown that a protein poised between a pair of electrodes could act as an efficient conductor of electrons. Proteins may have better conductance properties than similar nanowires composed of DNA. The expanded alphabet of 20 amino acids used to construct them offers an enhanced toolkit for nano architects when compared with just four nucleotides making up DNA. The researchers used protein segments in four nanometer increments, ranging from 4-20 nanometers in length. When the protein nanowires exceeded six nanometers in length, their conductance outperformed molecular nanowires. The data showed that […]
