(Phys.org)—The base-pairing properties of DNA, combined with our abilities to create synthetic DNA in the laboratory have led to advances in nanoscale architecture and molecular device designs. Less research has been done with proteins, even though proteins, like DNA, are made of individual subunits whose unique chemical properties can be exploited to functionalize protein sheets or immobilize the proteins on a surface. Certain proteins have desirable properties for molecular devices.
A mechanism of growth of anisotropic metal oxides that was predicted 20 years ago has been observed for the first time by researchers at the University of Bristol. The fabrication of nanowires of ternary and quaternary functional materials has become an important goal for their application in miniaturized circuits as diodes and transistors, coaxial gates and sensors.
