Nanotechnology: why is there silver in my socks?

WebNanotechnology. This GCSE Chemistry quiz is all about nanotechnology - the handling of matter on an atomic level. In 1981, Gerd Binnig and Heinrich Rohrer developed the scanning tunneling microscope. This is an instrument for imaging the surfaces of matter at the atomic level, for which they received the Nobel Prize in Physics in 1986. WebNanoparticles are usually distinguished from microparticles (1-1000 µm), "fine particles" (sized between 100 and 2500 nm), and "coarse particles" (ranging from 2500 to 10,000 nm), because their smaller size drives very different physical or chemical properties, like colloidal properties and ultrafast optical effects or electric properties.
