Nanotechnology concentrates on structures that measure only a few (up to several hundred) nanometers. Those are the smallest structures that can be generated from material, because structures below one nanometer are already on the scale of single atoms.

Nanotechnology deals with diverse substances that have different effects and are therefore used in very different fields of technology - not only in the shape of nanoparticles, but also as wires with diameters in the nano-range and in the form of thinnest material layers. Nanotechnology involves production methods for electronics as well as coatings of optical elements or particulate agent transport for medicine. Thus, nanotechnology is so versatile that it cannot be related to one single natural science like chemistry or physics. Every "nanotechnologist" is specialized in his own field.

Within the last years, nanotechnology has provided new approaches and solutions for many social fields. Among others, it will contribute to a world-wide reduction of energy and material consumption and help single humans by means of new diagnosis and therapy tools.

Particular is involved in the field of nanoparticles. These sub-microscopic "material nuggets" unfold special effects due to their large share of surface atoms. Half of all nanotechnology efforts world-wide are based on nanoparticles. They can be mixed with material, attached to surfaces, or used as single functional units that bind to biomolecules. Applying a new universal production method for nanoparticles, Particular contributes to the perspective that everybody will benefit from even more nano-products in the future.
