Nanotechnology involves manipulating and engineering materials at the nanoscale, between 1 to 100 nanometers. At this scale, materials can exhibit different properties than usual. For example, arranging carbon atoms in different ways produces graphite or diamonds. Gold nanoparticles can be various colors depending on their size and shape. Nanotechnology has applications in areas like faster computers, intense paints, cancer treatment, and longer-lasting batteries with smaller granules. While still a young field, nanotechnology has significant potential to advance many products and impact many areas of life.
