What is Nanotechnology?

Study and use of structures between 1 and 100 nanometers

○ nano.gov

“The study of phenomena and fine-tuning of materials at atomic,

molecular and macromolecular scales, where properties differ significantly from those at a larger scale.” ○ understandingnano.com

SLIDE 3

The Short History of Nanotechnology

The first discussion of nanotechnology-like-science took place in

1959 ○ “There’s Plenty of Room at the Bottom”

Term was coined by Professor Norio Taniguchi in 1974

○ Discussed technology on the order of a nanometer

1981 - IBM(Zurich) invented the STM

○ Scanning Tunnelling Microscope

In the late 90s early 00s, every developed nation opens a

nanotechnology initiative.

How is Nanotechnology Implemented Today?

15-20 nanometer wide water

filters

Nanofibers in clothing
Nanocomposite materials for

vehicles

SLIDE 6

How is Nanotechnology Implemented Today? Cont.

Chemical sensors
Nanoparticles in

medications

SLIDE 7

The Possible Future of Nanotechnology

Killing cancer cells and rebuilding bones
Catalysts to clean up carbon dioxide emissions
Self-cleaning materials
Dielectric resonators
Doomsday Scenarios (Runaway Technology)

Ethical Dilemma surrounding Nanotech

Many of the risks seen come from the medical side of

nanotechnologies implementation ○ Current issue causing lung damage ■ Still unsolved ( Forbes.com story)

Many companies go unchecked with their work

○ Wild west kind of work. Make now, rules later.

The world could turn into “gray goo”
Very hard to judge with its many different applications

SLIDE 9

Ethical Dilemma Cont.

Could reach a point to be

weaponized

Nanotoxicology

SLIDE 10

Ethical Dilemma Cont.

Unknown surveillance/spying

○ Creates a possible surveillance state

SLIDE 11

Ethical Analysis of Nanotechnology

Kantian Analysis

○ The intent of nanotechnology must be for the advancement

f the human race

○ Work on the lives of others and not for yourself ○ Breaking any guidelines that will be set in place will be seen as unethical

SLIDE 12

Ethical Analysis Cont.

Rule Utilitarianism

○ Working for the good of mankind ○ Follow rules set in place to keep a groups work just ○ By applying nanotechnology for good, the risks of all dangers will decrease ○ Exceptions to future guidelines should be prohibited due the the possible dangers of this technology
