Site-Specific Deposition of Gold Nanoparticles on SWNTs

Controlling matter at the nanoscale holds a lot of promise in nanotechnology. The DNA origami is promising if used as a template to design and arrange matter at the nanoscale. We have used the DNA origami approach to engineer staple strands at selected sites for attachment of gold nanoparticles. The covalent attachment of thiol-modified DNA oligomers was used to functionalize gold nanoparticles. These oligomers then hybridize with complementary strands extended on selected staple strands on the DNA origami surface with nanometer precision. Gold nanoparticles of 5 nm diameter were arranged across a DNA origami tube to form a C -shape which has potential use in electronics and plasmonics. Agarose gel electrophoresis, AFM, UV-Vis spectroscopy and TEM were used to characterize the structure.

Wet Chemical

An overview of various approaches to synthesize gold nanoparticles (AuNPs) bearing one single chemically addressable unit and their diverse fields of application is presented. This comprehensive review not only describes the strategies pursued to obtain monofunctionalized AuNPs, but also reports their behavior as 'massive' molecules in wet chemical protocols and the scope of their applications. The latter reaches from site-specific labels in biomolecules over mechanical barriers in superstructures to building blocks in hybrid nano-architectures. The complementing physical properties of AuNPs combined with precise chemical control of their attachment makes these objects promising building blocks for numerous proof-of-concept experiments and applications.
