Part 1: Introduction[edit]
Nanotechnology is the modern technology of micro subsctances.The branch of technology that deals with dimensions and tolerances of less than 100 nanometres, especially the manipulation of individual atoms and molecules .The pdf below will you give brief explanation about Nanotechnology.

Part 2: Seeing 'Nano'[edit]
These are the instruments that nanotechnologists use to 'see' very small objects that present themselves on the nanoscale (a billionth of a meter).

Part 3: Physics on the Nanoscale[edit]
How do things move, and what are the important forces on the nanoscale? It is very important to know these forces, and to take them seriously. This is because as you get smaller and smaller, the forces you think are weak - or don't even notice - take much greater effect.

Nanotubes and wires[edit]
The basis for a huge amount of nanotechnology, these nanowire and tubes come in several types such as Singlewall carbon nanotubes (can be metallic or semiconducting), multiwall nanotubes as well as various bamboo-structures or nanofibers/whiskers/coils.

Fluorescing Quantum Dots[edit]
These begin to have many uses in biological tag systems (among others). This is because quantum dots can have very stable fluoresence unlike fluorescing molecules that are prone to bleaching and influenced by the environment. The fluorescent color can be tune by the particle size.
