Abstract

The use of bio-molecular building blocks opens a new direction in the realm of nanotechnology and such a technology is essential to manipulate nanocrystals in its shape and size. Nucleic acids are of special interest for its ability of self-organization and sensitivity to biological process. In the present work, we present an approach of organizing bioinorganic nanostructures. CdSe nanowire has been synthesized using single strand oligonucleotides as a biotemplate by an electrodeposition technique. A comparative study conceded between CdSe nanoparticle and biotemplated CdSe-DNA nanowire. The CdSe-DNA nanowire reveals a cubic phase as revealed from X-Ray diffraction measurement. CdSe nanowires are fabricated in a filamentary, wire like morphology in DNA strand as established from Atomic Force Microscopic (AFM) measurements.
