At the nanoscale, many common materials exhibit unusual properties, such as
remarkably lower resistance to electricity, or faster chemical reactions
![Page 12: A sheet of paper is about 100,000 nanometers thick](https://reader036.vdocument.in/reader036/viewer/2022062423/56649e7b5503460f94b7cdda/html5/thumbnails/12.jpg)
Gold nanoparticles appear red (as well as orange, purple or green, depending on the size or shape of the particle) and melt at much lower temperatures than bulk gold, like that
used in jewelry

Aluminum nanoparticles spontaneously combust (increased reactivity), but an
aluminum can of soda doesn’t react with the air around it

Nanotechnology is the manipulation of material at the nanoscale to take advantage
of these properties
