Self-organisation/self-assembly in nano/micro systems

The number of particles in nano-and microscale systems is usually small. According to statistics, the ratio of the standard deviation of property A to the mean value of A, is in inverse proportion to the square root of the number of particles TV. In the macroscopic world, the deviation from the mean value is very small since the number of molecules is immense, whereas in the nano-and microscopic world, the deviation or fluctuation become significant. Here, I investigate self-organisation/self-assembly occurring in (a) a ferromagnetic nanoparticles disperse system, (b) a paramagnetic microparticles disperse system, (c) critical fluid systems and (d) bio-nano interactive systems, and show a variety of structures created in the above systems.
