| Abstract: | In this work we describe the formation of 1-dimensional (1D) assemblies of cysteamine functionalized gold nanoparticles on
DNA using the complex cis-Pt (cis-Pt(NH3)2Cl2) as site specific linker and their immobilization on mica and silicon. The characterization by atomic force microscopy and
electron microscopy served as complementary methods. Using atomic force microscopy with additional information of phase images
the DNA as well as the Au particles can be visualized independently and be differentiated in the 1-dimensional aggregates.
Electron microscopy shows individual particles are arranged as a string of pearls.
