The age of nanotechnology has arrived
The way to follow is to begin with the simplest tasks. The first stage is to manufacture nanostructures that in turn produce materials that are able to perform a single task. This is the stage that is more advanced. Most current commercial applications of nanotechnology are related with new materials.
A second stage is the fabrication of nanostructures most active, so they are able to detect substances, to move, to deliver a drug to specific diseased cells or to generate or adsorb the least amount of light. This is the stage where current research is focused.
Controlled growth of aligned carbon nanotubes in different patterns.
A third step would be to learn how to organize and interconnect nanostructures to harmonize their responses within a larger system. For example, the interconnection of power generating nanostructures that require energy to carry and move loads or a few other nanostructures.
A further step would be the manufacture of advanced nanosystems with thousands of components that interact with each other in a structured way. It has opened to us a box with new tools and ‘nano-bricks “that have extraordinary possibilities to find technological solutions to current needs in very varied fields. And like any new scientific discovery and technological development, we must bear in mind the responsibility to investigate possible adverse effects for the health of human beings and the environment.
