We report a virus-based scaffold for the synthesis of single-crystal ZnS, CdS, and freestanding chemically ordered CoPt and FePt nanowires, with the means of modifying substrate specificity through standard biological methods. Peptides (selected through an evolutionary screening process) that exhibit control of composition, size, and phase during(More)
The characterization of a bioelectronic composite prepared by molecular wiring of a bacterial photosynthetic reaction center (RC) to a metal (Au) electrode is described. Two unique attachment sites on the protein surface were studied as sites for electrical connections--a polyhistidine tag introduced by site-directed mutagenesis and a native cysteine amino(More)
Anisotropic, noble metal nanoparticles have been synthesized using a template synthesis strategy. In short, metallic salts are reduced in the nanometer scale pores of either an alumina or polycarbonate membrane. The particles can then been released from the template to form suspensions of anisotropic nanoparticles. These nanoparticles have been modified(More)
