Part 1: Introduction[edit]

This part will give you a general overview of nanotechnology.

PDF files[edit]


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).

Optical Microscopy[edit]

Electron Microscopy[edit]





Scanning probe microsocpy[edit]

Atomic Force Microscopy (AFM)[edit]

These figures for some odd reason wont show in the gallery display mode...

Scanning Tunneling Microscopy[edit]

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.

Part 4: Nanomaterials[edit]

The typical nanostructures and their functionality.


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.

Buckminsterfullerenes (Buckyballs)[edit]

Buckminsterfullerenes, affectionately known as 'buckyballs'.

Quantumdots and Nanoparticles[edit]

These are nanoscale particles of various materials.


Nanoparticles in dispersion. A nanoparticle dispersion is also called a sol.

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.

Part 5: Nanosystems[edit]

Fundamental electronic, optical, mechanical, and fluidic systems that can be made with nanostructures.

Part 6: Nanoengineering[edit]

How to make nanostructures integrated into useful devices.

Electron beam deposition[edit]

Part 7: Nano Bio-Primer[edit]

An important part of nanotechnology is to interface with living organisms.

Part 8: Environmental Nanotechnology[edit]

Should we worry about nanotechnology? Used wisely it can help improve our lives and the environment, and used ignorantly it can very likely cause damage as with all other technologies if abused.

Part 9: Global Outcome If Successful[edit]

Nanotechnology, of course may at first glance be considered dangerous and or destructive, which would only apply if it were to go wrong. If some of the more spectacular technologies ( e.g. self assembler) were to become successful, then it would perhaps be the greatest scientific advance since humans achieved spaceflight and walked on the moon.
