Because the thiol group was modified at phosphate site between C1 and C2 of 5′ end, the spatial exposure of DNA residue at C1 site was preponderant compating with the spatial exposure of the nanoparticles when the DNA renatured. The experimental result showed DNA renaturation ratio is about 50% and CdS nanoparticles were assembled into parallel quadrilateral array as the DNA renaturation progressed.展开更多
