DNA assisted fragmentation of nickel nanoparticle clusters and their spectral properties.
Nickel nanoparticle (NiNP) clusters in the range of 60-70 nm size on interaction with herring-sperm DNA (B-DNA) form a self-assembled duplex helix DNA structure with fragmented NiNPs as small as 5-15 nm, 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 studies.
