Infrared Lasers in Nanoscale Science

In the nearly half a century scientists have already realized that, just as Feynman predicted, there is plenty of research room at the bottom of the matter world in a tiny universe so small that new methods for viewing it are still being discovered. Actually, nanoscience and nanotechnology have evolved into a revolutionary area of technology-based research, opening the door to precise engineering on the atomic scale and affecting everything from healthcare to the environment. Nanoscience research and education lead to nanotechnology, the manipulation of nanometer-length atoms, molecules, and supramolecular structures in order to generate larger structures with superior features. Because all natural materials and systems exist at a nanoscale level, nanotechnology impacts a variety of scientific fundamental and applied disciplines, from physics to medicine and engineering. Nanomaterials consisting of nano-sized building blocks exhibit unique and often superior properties relatively to their bulk counterpart. Due to the fact that most of the novel properties of nanomaterials are size-dependent, synthesis methods leading to better control of size, distribution and chemical content of the nanoparticles are imperative in modern nanotechnologies.
