Nanotechnology Risks - The Bigger Picture for Business and the Importance of 'Due Diligence'

The holistic process of risk analysis, advocated and practiced by SAFENANO - the UK's MNT Centre of Excellence in Nanotechnology Safety - is the basis of the assessment, management and communication of potential harm from substances, processes or technologies.

Bionanotechnology - Combining Nanotechnology with Biology

If we define nanotechnology as the application of materials and devices with characteristic (i.e. property determining) length scales between 1 and 100nm to the development of new products and processes; then bionanotechnology is its interface with biological systems.
