They range in size from about 100nm down to about 1nm.

usally thr size of small molecules, to small to see with a microscope.

They have a large surface area compared with their volume. This enables them to react very quickly which makes them useful as catalysts to speed up reactions.

They have different properties to the same substance in normal-sized pieces.
