ABSTRACT

The prefix “nano” has found in last decade an ever-increasing application to different fields of the knowledge.[1] Nanoscience, nanotechnology, nanomaterials or nanochemistry are only a few of the new nano-containing terms that occur frequently in scientific reports, in popular books as well as in newspapers and that have become familiar to a wide public, even of non-experts.[2] The prefix comes from the ancient Greek through the Latin nanus meaning literally dwarf and, by extension, very small. Within the convention of International System of Units (SI) it is used to indicate a reduction factor of 109 times.[3] So, the nanosized world is typically measured in nanometers (1nm corresponding to 10-9 m) and it encompasses systems whose size is above molecular dimensions and below macroscopic ones (generally > 1 nm and < 100 nm).[4]
