Nano-, what means?

    Nano-----, what means?

    What is a nanoblade? And a nanospring?
    I am not an expert about nanotechnology but I would like to understand something more.
    Thanks in advance.

    Nano is a prefix meaning 1 billionth of something. So a nanometer is 1 billionth of a meter. Nanotechnology is generally referring to something that is on the scale of nanometers. So a nanoblade and nanospring are simply a spring and a blade that are a few nanometers to a few hundred nanometers in size or so.

    Nanotechnology is the study and design of technology on the nanoscale, whilst this technically ranges from 1-1000nm in the field it refers to 1-100nm because this is the scale at which materials start to take on unique properties separate to their larger counterparts.

    Also, if the numbers are difficult to visualize... If a marble were 1 nanometer in diameter, 1 meter would be the diameter of the Earth.

    I find this neat little http://www.newgrounds.com/portal/view/525347" [Broken] good for understanding the scales involved
