In this paper, a method for highly ordered assembly of cuprous oxide (Cu2O) nanoparticles (NPs) by DNA templates was reported. Cetyltrimethylammonium bromide (CTAB)-capped Cu2O NPs were adsorbed onto well-aligned lambda-DNA chains to form necklace-like one-dimensional (1D) nanostructures. UV-vis, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) were used to characterize the nanostructure. The Cu2O nanostructures fabricated with the method are both highly ordered and quite straight. (c) 2005 Elsevier B.V. All rights reserved.
