Developing non-lithographic techniques for assembly of nano-scale materials metals, semiconductors at the interface between nano-materials and biology offers a glimpse into the design of potential materials for optical or electronic devices. Materials assembly using biological polymers DNA, proteins as scaffolds to direct the assembly of nano-scale components semiconductors, metals offers an exciting possibility of blending the inherent self-assembling properties of biological materials and the unique electronic and optical properties of nanomaterials. We have investigated the assembly of nano-scale materials Au, Ag, CdSe into 3-d super-lattices of nano-particles connected by biological polymers DNA, polypeptides, in which the biological spacers act as molecular level scaffolds for nano-assembly.
