Resumen
Resumen. El término “nanotecnología” es empleado para definir las ciencias y técnicas que se aplican a nivel de nanoescala (10-9m), y permiten trabajar las estructuras moleculares y sus átomos, lo cual da la posibilidad de fabricar materiales y máquinas a partir del reordenamiento de átomos y moléculas. Esta disciplina históricamente se inició en 1959, a partir de las propuestas de Richard Feynman, las cuales fueron tan significativas, que actualmente es reconocido como el padre de la nanociencia. Básicamente, la nanotecnología es el estudio, diseño, creación, síntesis, manipulación y aplicación de materiales, aparatos y sistemas funcionales a través del control de la materia a nanoescala, y la explotación de fenómenos y propiedades de la materia a esa escala. Desde 1959, los descubrimientos relacionados con la nanotecnología y sus aplicaciones han aumentado de manera exponencial. Uno de los más importantes han sido los nanotubos de carbono (NTC); fueron descubiertos en Japón por Sumio Iijima en 1991; poseen excelentes propiedades mecánicas y eléctricas. Algunas de las múltiples aplicaciones (presentes y futuras) incluyen a los nanotransistores, almacenamiento de hidrógeno, aumento de la sensibilidad de los microscopios de fuerza atómica (AFM), detección de contaminantes, materiales superresistentes y superconductores. El físico de la Universidad de Stanford en California, Hangjie Dai ha descubierto que nanotubos de carbono con una longitud de 2000 nanómetros, pueden detectar amoníaco y óxido nitroso .
Abstract. The term “nanotechnology” is used to define the sciences and techniques that are applied at the nanoscale level (10-9m), and allow working on molecular structures and their atoms, which gives the possibility of manufacturing materials and machines from rearrangement of atoms and molecules. This discipline historically began in 1959, based on the proposals of Richard Feynman, which were so significant that he is currently recognized as the father of nanoscience. Basically, nanotechnology is the study, design, creation, synthesis, manipulation and application of materials, devices and functional systems to through the control of matter at the nanoscale, and the exploitation of phenomena and properties of matter at that scale. Since 1959, discoveries related to nanotechnology and its applications have increased exponentially. One of the most important has been carbon nanotubes (CNT); They were discovered in Japan by Sumio Iijima in 1991; They have excellent mechanical and electrical properties. Some of the many applications (present and future) include nanotransistors, hydrogen storage, increasing the sensitivity of atomic force microscopes (AFM), contaminant detection, super-resistant and superconducting materials. Physicist at Stanford University in California, Hangjie Dai, has discovered that carbon nanotubes with a length of 2000 nanometers can detect ammonia and nitrous oxide.
