ABSTRACT
The effect of nanoparticle (NP) concentration was examined on the formation of heterostructured nanowires fabricated using DNA as a template. At mass ratios of 1:1 DNA:NP, the circular dichroism (CD) data showed a distinct characteristic, a plateau at 260 nm. The magnetic force microscopy (MFM) data revealed segments that showed variable interaction with the magnetized tip. At high NP concentrations both the CD and MFM data confirmed that the DNA template denatures and the control over the assembly process is poor.
