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 ○

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

How is Nanotechnology Implemented Today? Cont. Chemical sensors ● Nanoparticles in ● medications

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 ●

Ethical Dilemma Cont. Could reach a point to be ● weaponized Nanotoxicology ●

Ethical Dilemma Cont. Unknown surveillance/spying ● Creates a possible surveillance ○ state

Ethical Analysis of Nanotechnology Kantian Analysis ● The intent of nanotechnology must be for the advancement ○ of 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

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
