Nanotechnology may be able to create many new materials and devices with a vast range of applications, such as in medicine, electronics, biomaterials and energy production. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the nanotoxicity and environmental impact of nano materials, and their potential effects on global economics. Like electricity or computers before it, nanotech will offer greatly improved efficiency in almost every facet of life. But as a general-purpose technology, it will be dual-use, meaning it will have many commercial uses and it also will have many military uses making far more power -full weapons and tools of surveillance. Thus it represents not only wonderful benefits for Humanity, but also grave risks. A key understanding of nanotechnology is that it offers not just better products, but a vastly improved manufacturing process. A computer can make copies of data files—essentially as many copies as you want at little or no cost. It may be only a matter of time until the building of products becomes as cheap as the copying of files. That's the real meaning of nanotechnology and why it is sometimes seen as "the next industrial revolution." Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometers. Quantum mechanical effects are important at this quantum-realm scale. In this project a discussion about each method and its principle, applications, and limitations are done in details. These techniques are discussed in detailed further. Applications for the future: Efficient and energy-saving Cube-shaped nanostructures known as metal organic frameworks (MOFs) are the storage medium of the future.Keywords

Among the different extraction techniques used at analytical and preparative scale, supercritical fluid extraction (SFE) is one of the most used separation technique, which mostly depends on critical temperature and pressure of supercritical fluid. This review covers the most recent developments of SFE indifferent fields (SFE applications), such as food science, natural products, by-product recovery, pharmaceutical and environmental sciences, during the period 2007-2009. The revision is focused on the most recent advances and applications in the different areas; among them, it is remarkable the strong impact of SFE to extract high value compounds from food and various natural products but also its increasing importance in areas such as heavy metals recovery, enantiomeric resolution or drug delivery systems.Keywords
