Abstract

We report on a new method to make nanostructures in aqueous solution at room temperature. We used the protein cytochrome c₃ to catalyze reduction of selenate (SeO₄^2-) to selenium Se⁰ by dithionite. Reduction was instantaneous. After a week spherical nanoparticles of red Se⁰ (about 50 nm diameter) precipitated, followed by self-assembling into crystalline nanowires, typically 1 μm long. The nanowires were composed of one strand of spherical particles; thicker strands contained several nanoparticles in parallel.
