Highly organized CdS growth by DNA templating is used to produce either linear arrangements of Q-particles along the DNA strands or continuous conducting nanowires (see figure). By optimizing the reaction conditions, the potential of biopolymers in general and DNA in particular for producing nanometer-scale electronics is exemplified.
