Introduction to nanoscience, via WWW, Aug. 1, 2002 (Nanoscience is a growing field of research in chemistry, physics and biology with sweeping implications for new technologies; one definition of nanoscience is that it concerns itself with the study of objects which are anywhere from hundreds to tens of nanometers in size; nanoscience is an emerging area of science which concerns itself with the study of materials that have very, very small dimensions. It can't really be called chemistry, physics, or biology; all sorts of scientists are studying very small things in order to better understand our world.)

In view of this, it is natural that scientists which are trained in different fields will adopt different definitions. Nanoscience may be defined as the research concerned with physical objects for which the nanometer length-scale is crucial. In chemistry, it may be a synthesized supramolecular molecule, in biology a protein, or the pore of a cell membrane. In solid-state physics, it is a piece reduced in size in one or more dimensions to -- depending on the taste -- below 1 micron or below 100 nm. This definition is extremely wide, as it includes everything listed below: surface science (lattice reconstructions, adhesion, growth), thin films (also monolayers), interfaces (multilayers, wetting properties), internal interfaces (grain and domain boundaries, phase segregation, dislocations ...), devices (state-of-the art transistors), virtually all microscopy starting from scanning-optical confocal microscopy, over electron microscopy to all kind of scanning-probe microscopes. During recent years, a narrower definition of nanoscience has been established. Accordingly, nanoscience is concerned with the controlled investigation of single entities of nanoobjects, e.g. molecules. Because manipulation is one of the key for the investigation, nanotechnology is an extremely important part of all nanoscience. Furthermore, nanoscience is challenged by the fact that single entities yield tiny measurable signals. Therefore, measuring for example the mass of molecules, electric current with single electron accuracy, or measuring magnetic moment with single-spin resolution are important goals for the future progress of nanoscience.")
