The AZoNano.com "Nanotech Thought Leaders" series is a collection of articles that cover the key technology areas where Nanotechnology is making an impact and where it will make an increasing impact. All the articles are written by experts who have been invited as recognised leaders in their fields to provide a "state of the art" contribution.
This article outlined how nanotechnology is being used for water purification. In particular it focuses on biofouling resistant silver-polysulfone composite membrane.

The field of sensors encompasses a wide variety of materials and devices used for capturing physical, chemical or biological stimuli converting them to measurable output signals.
Hexagonal boron nitride (h-BN) is a layered material with a graphite-type structure in which planar networks of BN hexagons are regularly stacked.
Numerous research articles have examined the sensitivity of the relationship of scale, structure, composition, and emergent properties of nanomaterials to their behavior in biological systems and the environment.
In Farfield, our work over the past decade has revolved around the direct measurement of the shape or conformation of biomolecules and how this changes as the biomolecules function.
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.
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.
The definition of nanocomposite material has broadened significantly to encompass a large variety of systems such as one-dimensional, two-dimensional, three-dimensional and amorphous materials, made of distinctly dissimilar components and mixed at the nanometer scale.
Professor Narayan and his colleague at Joint Department of Biomedical Engineering, University of North Carolina and North Carolina State University have recently performed several studies to examine the use of atomic layer deposition for modifying the surfaces of nanoporous alumina membranes.
