Nano Technology and Robotics Placement

It is a tiny materials Science. when we say "NANOSCIENCE" it means that the behaviour and the formation science of a material at the nanometer scale (10^-9 m) and when we say nanotechnology it means that with the understanding of science and mechanism the formation of a helpful device or a system with nanometer scale.it is interesting.NOTE: the behaviour and properties change with the size so same materials behave differently when it will be in bulk and also at the nanometer scale.hope I have satisfied your question.Have a great day.take care.
