Abstract
CdSe nanocrystals (NCs) with good crystallinity were successfully grown by an electrochemical deposition technique using two different single stranded (ss) DNA molecules, poly G (30) and poly C (30) as templates. A model describing the structural ordering in CdSe NCs using ssDNA and its conjugate is being proposed. TEM and GXRD measurements confirm the structural ordering in NC CdSe–DNA systems. FTIR measurements confirm the tagging of DNA to CdSe NC. Micro Raman scattering of structurally ordered CdSe NCs show strong phonon confinement.
