摘要

The nano-scale spatial organization of metallic and other inorganic materials into 1D objects is a key task in nanotechnology. Nano-scale fibers and tubes are very useful templates for such organization because of their inherent 1D organization. Fibrillar biological molecules and biomolecular assemblies are excellent physical supports on which to organize the inorganic material. Furthermore, these biological assemblies can facilitate high-order organization and specific orientation of inorganic structures by their utilization of highly specific biological recognition properties. In this minireview, I will describe the use of biomolecules and biomolecular assemblies, including DNA, proteins, peptides, and even viral particles, which are excellent templates for 1D organization of inorganic materials into wires. This ranges from simple attempts at electroless deposition on inert biological templates to the advanced use of structural motifs and specific protein-DNA interactions for nano-bio-lithography as well as the fabrication of multilayer organic and inorganic composites. The potential technological applications of these hybrid biological-inorganic assemblies will be discussed.
