movimiento de un glóbulo rojo a medida que avanza por su vena, o poder observar cómo un tipo de glóbulo blanco (llamado “célula T”) destruye un microbio invasor envolviéndolo. ¿Cómo sería observar la vibración de las moléculas a medida que aumenta la temperatura en un recipiente con agua? ¿Observar los átomos de sodio y cloro a medida que se acercan lo suficiente como para transferir electrones y formar un cristal de sal? Nuevas herramientas científicas, desarrolladas y mejoradas durante las últimas décadas, hacen posibles tales observaciones. Estos son ejemplos del esfuerzo por ver, medir y manipular materiales a escala molecular o atómica; este esfuerzo es el foco principal de la nanotecnología.</p> <p>El prefijo “nano” proviene de una palabra griega, νᾶνος, que significa “enano”. Este prefijo se utiliza en el Sistema Internacional de Unidades (SI) para indicar un factor de 10<sup>−9</sup>. Si tenemos el prefijo “nano” adjunto a un metro (m), entonces 1 nm (nanómetro) = 10<sup>−9 </sup>metro (una milmillonésima parte de un metro, según la definición de “escala corta” de mil millones utilizada en varios países). Si el prefijo se adjunta a un segundo (seg), entonces 1 ns = 10<sup>−9 </sup>segundo (1 milmillonésima de segundo).</p> <p>Las herramientas que nos han permitido observar el mundo antes invisible de los objetos a nanoescala incluyen microscopios especiales y sofisticados como el <a href="https://trynano.org/es/education-resources/nanotechnology-glossary/">Microscopio de fuerza atómica</a> y el <a href="https://trynano.org/es/education-resources/nanotechnology-glossary/">Microscopio de efecto túnel</a>.</p> </div> <div class="sidebarCol"> <img src="https://trynano.wpenginepowered.com/wp-content/uploads/2020/06/whatisnano.jpg" /> <span>Ilustración 3d de la estructura del tubo de grafeno.
