Basic Definition: Basic Definition: Technology of building or creating products such as electronic circuits from single atoms and molecules• Deals with the making of materials by molecular self

assembly• Rearranging atoms to get:

Manufactured products:Manufactured products: made from atoms

Properties of products:Properties of products: depends on how atoms are arranged

For instance, if we rearrange the atoms of coal, we can make diamond if we rearrange the atoms in dirt water or air, we can end up with potatoes!

In the future nanotechnology can:In the future nanotechnology can:1. Easily move and put atoms together2. Be accomplished inexpensively 3. Be accomplished with help by the laws of physics4. Help us make products more cleaner, stronger, lighter and

more precise

Nanotechnology will help us :Nanotechnology will help us :1. Develop new manufacturing technology2. Help us build computer systems inexpensively with mole

quantities

Nanotechnology will assure that :Nanotechnology will assure that :1. Every atom is in the right place2. Make almost all products with the help of laws of physics3. Manufacturing prices will not go higher than the price at

which the raw materials were bought for

Improved products Improved products rely on change in physical properties

Nanoparticles Nanoparticles take advantage of increased surface area over volume

ratio strongly change the mechanical properties of material

(e.g. makes it light and increases stability)

With the help of Nanoparticles, which are the size of molecules, drugs can directly be delivered to diseased cells in the body

Drug deliveryDrug delivery Iron nanoparticles or gold shells can be used to treat

cancer

Tissue engineeringTissue engineering Nanotechnology can help reproduce and repair

damaged tissue

Nanotechnology helps reduce waste and materials and enhances renewable energy resources

Recycling of BatteriesRecycling of Batteries Batteries have low energy density and it also needs

recharging Can lead to disposal problems

Nanomaterials can be used to help increase higher rate of recharging and energy of batteries

This is essential for disposal problems

• Concerns exist about the possible impacts of manufactured nanoparticles and nanotubes that are free to move around Free nanoparticles could be inhaled or enter the body

through the skin, and cause damage to cells Nanoparticles can affect plants and animals by

entering the food chain Nanotubes, when inhaled, can cause respiratory

problems• Small sensors can be used to spy on people

It is right because:It is right because:1. It will make world a better place2. It is likely to reduce other ethical issues (e.g., constructing

cells rather than getting them from reproduction) 3. It will give us more “god-like” powers

It is wrong because:It is wrong because:1. It will give us more “god-like” powers 2. It may lead to undetectable surveillance; right to privacy

could be at risk
