Good morning, today I bring you a topic that catches my attention and is that of nanotechnology; As it is possible that such a small particle, do so much for us, for that reason, it seemed important to transmit the advances that have been made with respect to this technology in countries that are still in development.

Nanotechnology and its applications in developing countries

Nanotechnology can be mastered to address many of the most critical development problems and in recent years there have been several efforts to better systematize these possible contributions. For example, the Meridian Institute of the United States chose certain sectors with greater application potential and convened specialists in nanotechnology, in the development of public policies, academics, and dialogues in workshops. The first one executed in Chennai, India in October 2006, dealt with water applications. The Workshop discussed on the basis of previously prepared studies, which identified a set of instruments and devices that already incorporate nanotechnology and are in the market or that are in an advanced stage of development, and that are:

• Membranes for nanofiltration, including desalination technologies
