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.
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.
This review will focus on carbon nanotubes attached on larger graphitic solids, which can range from simple flat graphite to complex cellular foams having open-interconnected porosity.
The Nanomechanical Properties Group at the National Institute of Standards and Technology, under the leadership of Dr. Robert F. Cook, develops measurement techniques and standards to enable the use of materials in nanomechanical applications.
Nanotechnology has opened up innovative techniques for producing bone-like synthetic nanopowders and hydroxyapatite coatings. Although not called nanopowders, nanoscale materials have existed since the dawn of science using a range of chemical routes.
Nanotechnology and the use of unbound engineered nanoparticles (UNP) is a rapidly developing area of material science.
The quest is on for high power and energy density power sources at ever smaller sizes for applications ranging from on-chip sensors to insertable pharma-delivery to flying microrobots to more mundane applications powering PDAs and computers.
