Descubrimiento clave de DuPont en el campo de la nanotecnologíaKey discovery of DuPont in the field of nanotechnology
on December 26, 2003
A scientific team led by DuPont has discovered an innovative method to sort of carbon nanotubes by means of DNA which offers enormous potential for use in nanotechnological applications. The results of this research in the emerging field of nanotechnology appear in the latest issue of the journal Science, which publishes the AAAS (American Association for the advancement of science), the largest scientific institution in the world. The study is entitled "Structure-Based Carbon Nanotube Sorting by Sequence-Dependent DNA Assembly" (selection of nanotubes of structure of carbon through the Assembly of molecules of DNA patrón-dependientes).
The carbon nanotubes offer excellent properties such as electrical conductors, which makes them an important structural element in a wide range of electronic applications related to nanotechnology, including devices for the medical diagnosis of great sensitivity and minitransistores that are up to one hundred times smaller than employees in present microchips. To make, however, different electronic types carbon nanotubes are grouped at random, thus decreasing the consistency of the driver. Get order and grouped consistently carbon nanotubes provides a uniform conductivity, allowing these applications to be a reality.
