Abstract: CdSnanoparticles were synthesized by using two complementary 2′ phosphorothioate oligo DNA, oligoG 10-SH and oligo C10-SH as stabalizers. Because the thiol group was modified at phosphate site between C1 and C2 of 5′ end, the spatial exposure of DNAresidue at C1 site was preponderant compating with the spatial exposure of the nanoparticles when the DNArenatured. The experimental result showed DNArenaturation ratio is about 50% and CdSnanoparticles were assembled into parallel quadrilateral array as the DNArenaturation progressed.

Key words: DNA, CdS, Nanoparticle
