DNA molecules are useful building blocks and nanotemplates for controllable fabrication of various
bioinorganic nanostructures due to their unique physical−chemical properties and recognition capabilities
and the synthetic availability of desired nucleotide sequences and length. We have synthesized novel DNA
complexes with positively charged, highly luminescent CdSe nanorods that can be self-organized into
filamentary, netlike, or spheroidal nanostructures. DNA−CdSe-nanorod filaments possess strongly linearly
polarized photoluminescence due to the unidirectional orientation of nanorods along the filaments.
