There are two main ways to get into the nanoworld: molecular manufacturing that involves the manipulation of individual atoms (which work from bottom to top) and ultra miniaturization resulting in smaller and smaller devices (which work from top to bottom).
Nanotechnology is truly a multidisciplinary set of techniques arising from nanoscience.
Materials scientists, mechanical and electrical engineers are working with biologists, physicists and chemists. Research at nanoscale is related to the need to share knowledge about tools and techniques, as well as knowledge regarding atomic and molecular interactions, in this new scientific frontier.
Converge rapidly to different research areas new and powerful concepts and capabilities, such as the representation by images and manipulation at the atomic scale, self assembling and structure-function biological relationships alongside computer tools increasingly powerful.
Moreover, at the nanoscale, for changes made in the properties on a molecular scale of a material, strongly influences their physical and chemical properties at the macroscale.
The challenge is to increase the proportion of nanofabrication methods for mass production in industry.
Fundamental research is essential to exploit the full potential of nanotechnology. In the nanotechnology area, can be defined three main vectors: nanoelectronics, nanobiotechnology and Nanomaterials (nanocomposites).
The development of nanotechnology is of utmost importance, considering that the population today is concerned with the benefits from the nourished, resulting in well-being.
The industries will have to compete nationally and internationally with new products. This competition will become successful from the emergence of innovative products and processes that match or even exceed the best products offered by the international industry.
