Self-assembly of nanoparticles - a step towards realizing completely self-organized devices

The fabrication of ultrafine structures beyond the limits of conventional lithography is a topic of tremendous importance and is expected to play a significant role in the realization of futuristic nanotechnology. It is also equally important to develop functional material systems of ultrafine dimensions in order to achieve this goal. An important step towards realization of nanodevices is self-organized nanopatterning of functional structures. A new technique, which might be called chemical lithography, enables the regular assembly of optically active nanoparticles on a silicon surface.

Oscillating pattern in nanoparticle crystallization

In order to survive, biological systems need to form patterns and organize themselves. Scientists at the Max Planck Institute for Colloids and Interfaces (MPI-KG) in Potsdam, Germany, have now combined self-organization with chemical pattern formation. They demonstrated that oscillating reaction patterns like that of a Belousov-Zhabotinsky reaction can not only be generated in a one-phase system like in all previous examples but also in a two-phase system like liquid-solid.
