Nickel nanoparticle (NiNP) clusters in the range of 60–70nm size on interaction with herring-
sperm DNA (B-DNA) form a self-assembled duplex helix DNA structure with fragmented
NiNPs as small as 5–15nm, as evident from atomic force microscopic studies. Scanning
electron microscope (SEM) and transmission electron microscope (TEM) images also
corroborate the findings. The properties of these self-assembled NiNPs–DNA structures
have been further investigated by UV–visible, emission and circular dichroic (CD) spectral …
