What is nanotechnology

?


• Emergent phenomena• Convergence• Self-assembly• Self-replication• Bio-nanotechnology


?


• Emergent phenomenaAs the size of a crystal shrinks towards the size of molecules and

atoms, its electrons start to follow the laws of quantum mechanics

rather than classical mechanics, and behave more like waves than

like particles. The electrical and optical properties can be

dramatically changed just by changing the size.

• Convergence• Self-assembly• Self-replication• Bio-nanotechnology


?


• Emergent phenomena• Convergence

Progress in nanotechnology is dependent on understanding ideas

from physics, engineering, chemistry and biology: it is a multi-

disciplinary or convergent topic. This has implications for how we

teach science and how we structure research.

• Self-assembly• Self-replication• Bio-nanotechnology


?


• Emergent phenomena• Convergence• Self-assembly

Although most miniature devices are made by making small patterns

on large objects (“top down”), it may be possible to get better control

by assembling individual atoms or molecules into larger clusters

(“bottom up”). Self-limiting chemical or biological synthesis can be

used.

• Self-replication• Bio-nanotechnology


?


• Emergent phenomena• Convergence: • Self-assembly• Self-replication

borrowing ideas from biology, we can imagine machines which

reproduce themselves. This has given rise to some newspaper

stories about nanorobots taking over the world. Is this science fact or

science fiction?

• Bio-nanotechnology


?


• Emergent phenomena• Convergence• Self-assembly• Self-replication• Bio-nanotechnology

by making structures which are the same size as the components of

cells, we can start to manipulate biological processes, or make

sensors which are sensitive to a single molecule. Or, we can exploit

Nature’s nanotechnology, using DNA to assemble scaffolds or to

make biomolecular motors.

Governance and Corporate Social Responsibility in

Nanotechnology Industries

The project aims to provide a deeper understanding of the current and prospective role of governance models and of CSR in the nanotechnology industries and and subsequently communicate the findings to the relevant stakeholders.

What are the company drivers towards technology development and use in this sector? What are the drivers towards the application of CSR? What are the relevant legislation at UK, European Community and international levels?

What is the dominant mode of CSR and of governance in this industry, and how closely does it match modes in other industries?

To what extent and how are global principles, such as Duty of Care, Precautionary and Polluter Pays Principle recognised in the deliberation processes and the innovation drives?

Which, if any, pre-product screening methodologies are currently (or can be) applied, notably eco-toxicology, Life-cycle assessment, risk assessment, regulatory compliance assessment etc? What is their scope and remit?

What are the strategic drivers for industry to pursue and implement such technology drives? (Technology-push, Market-pull?

How effective is the de facto governance process to “future proof” technology and to identify long-term risk? How is uncertainty being assessed and managed, if any, in the strategic product design and manufacturing choices involving nanotechnology?
