Outline

What’s Nanotechnology?

The science of manipulating atoms and molecules to fabricate materials, devices and systems. Unlike current production methods, in which existing parts and components are combined, nanotechnology takes atoms and precisely assembles them to produce items with desirable characteristics….

Key words: nano-size, controllable, and novel properties.

Prospective and ethical issues of nanotechnology:

Utopian dreams Apocalyptic nightmares

Utopian dreams

1. Pollution-free environment

2. Ideal society

3. Disease-free life

4. Long and healthy life

Apocalyptic nightmares

1. War of the world

2. Epidermic of nanobots into the

food chain and ecosystems

3. Economic break-down

Ethical Issues of Nanotechnology

• Research ethics and the use of implanting nano-devices in humans: i.e. implanting artificial devices.

• Increasing of uneven military power• Increasing of economical gap between

developed and developing countries• Increasing possibilities of misused personal

information: i.e. revealing a medical information (in a DNA chip) to an insurance companies

• Increasing possibilities of privacy violation

Roles of NANOTEC in Safety & Ethical Issues

• A driving force of establishing nano-standardization and nano-labels

• Developing nano-safety guideline in Thailand

• Establishing nano-safety committee to monitor nanotechnological researches

• Participating in OECD nano-safety guideline working groups
