Abstract

DNA-conjugated gold nanoparticles exhibit a unique aggregation behavior that they form aggregation with fully complementary DNA but do not with the terminal-mismatched DNA at certain concentration of added salts. We studied the aggregation structure of the nanoparticles by small angle X-ray scattering (SAXS). The results indicated that the gap between surfaces of gold nanoparticles is nearly two times as long as DNA in B-form.This suggests that the ends of completely double-strand DNA conjugated on gold nanoparticles contact or interdigitate slightly with each other in the aggeregation structure.
