Nanotechnology is a field where scientific knowledge and ideas emanating from the sub-atomic, atomic and molecular levels are applied in the manufacture of new and smart materials. Nanotechnology makes use of the novel properties exhibited by materials in the nanoscale. Nanocrystalline materials have microscopic grain sizes of up to 100 nm with remarkably distinct optical, electrical, chemical, mechanical properties different from those of bulk materials. Nanoparticles can be used to develop materials with unique properties since the number of atoms on the surface of a particle in the nanoscale is comparable to that inside the particle. Hence in order to meet the advanced technological demands in the areas such as electronics, catalysis, ceramics, magnetic data storage, structural components etc., it is important to make use of materials in the nanometer scale. Nanotechnology is a rapidly growing field of science which encompasses researchers and scientists from the areas of biology, chemistry, engineering, materials science and physics. This technology provides the basis for research and manufacture of materials in the 21st century. In addition, this interdisciplinary technology will provide a strong platform for the growth of pharmaceutical industry, medical diagnosis, materials industry and the overall economy of the country which will eventually enhance creation of job opportunities, food security, good health and affordable housing in line with the government's "big four" agenda. It promises improved efficiency in ICT equipment used in computing, data storage (chips) and communications (fibre optics). It can be used to develop renewable energy sources such as solar cells and panels. It can also be utilized to synthesize filters that can be used to get rid of pollutants; contaminants, harmful salts and viruses in water and sewerage systems and for the diagnosis and treatment of diseases including cancer and to restore damaged human organs or tissues using engineered tissue.

Nanotechnology has been playing a tremendous role in all fields of life sciences including 13 cell biology, genetics, molecular biology, botany, microbiology, zoology, evolution, ecology, and 14 physiology. Applications of nanotechnology are more on applied side in different sectors from 15 industry to agriculture. Agriculture sector is the backbone of developing countries for their economy. 16 Growing world’s population is putting more pressure on agriculture sector and there is a need to 17 develop new technology to address the crises of food safety and food shortage. Today’s agriculture 18 has been entered in a new era where nanotechnology works as a technological advancement 19 regarding entire agriculture crops, and food sector revolution, even though, it has prodigious 20 applications in food production, food processing, food packaging, food storage and economic growth 21 of industries. Moreover, nanotechnology is the best solution to solve problems related to better food 22 a...

Food nanotechnology is an area of emerging interest and opens up a whole universe of new possibilities for the food industry. The basic categories of nanotechnology applications and functionalities currently in the development of food packaging include: the improvement of plastic materials barriers, the incorporation of active components that can deliver functional attributes beyond those of conventional active packaging, and the sensing and signaling of relevant information. Nano food packaging materials may extend food life, improve food safety, alert consumers that food is contaminated or spoiled, repair tears in packaging, and even release preservatives to extend the life of the food in the package. Nanotechnology applications in the food industry can be utilized to detect bacteria in packaging, or produce stronger flavors and color quality, and safety by increasing the barrier properties. Nanotechnology holds great promise to provide benefits not just within food products but also around food products. In fact, nanotechnology introduces new chances for innovation in the food industry at immense speed, but uncertainty and health concerns are also emerging. EU/WE/global legislation for the regulation of nanotechnology in food are meager. Moreover, current legislation appears unsuitable to nanotechnology specificity.

Nanomaterials and nanoparticles are not an invention of the twentieth century. Examples of nanostructured materials can be found throughout the fourth to the seventeenth century. Important examples are vividly colored stained glass windows in European cathedrals obtained through the use of gold nanoparticles; silver or copper nanoparticles used in the Islamic world to give luster to their ceramics; and finally carbon nanotubes and cementite nanowires present in the famous Damascus saber blades. These materials, showing unusual characteristics, were generally produced empirically by talented craftsmen, often through the use of high temperature. The intentional manipulation at atomic level or molecular scale to manufacture nanoparticles or nanostructured materials, however, requires the understanding and the control of matter at dimensions between 1 and 100 nm, approximately, and was possible only after the advent of high-powered microscopes, in particular the scanning tunneling microscope by Gerd Binning and Heinrich Rohrer in 1981, which for many marked the birth of nanotechnologies. From that moment, tools were developed that allowed imaging, measuring, modeling, and manipulating matter at nanoscale to achieve altered characteristics that could differ greatly from those on the macroscale. One should talk about nanotechnologies only if the correlation between the nanostructure of the novel materials and the resulting highly unique properties is recognized and deliberately applied. This criterion excludes naturally occurring nanoparticles and hence naturally formed biomolecules and material particles, and separates these from the particles resulting from nanotechnological applications. It is also clear from the above description of nanotechnologies that these encompass a whole group of different technologies and involve many different disciplines. Soon, several countries recognized the applicability of nanotechnologies in several different sectors such as medicine, biotechnology, electronics, materials science, energy, and more.
