Government regulations to address technological risks are important for the successful development and application of nanotechnology, but there is an ongoing debate in the USA about who is responsible for the regulation of nanotechnology. In a mail survey of leading US nano-scientists, we examine scientists’ perceptions about nano-regulation, including the government level (local, national, or ...

Nanotechnology is one of the most important tools in modern agriculture, and agri-food nanotechnology is anticipated to become a driving economic force in the near future. Agri-food themes focus on sustainability and protection of agriculturally produced foods, including crops for human consumption and animal feeding. Nanotechnology provides new agrochemical agents and new delivery mechanisms t...

543 N anotechnology is being hailed by many as the " next industrial revolution. " 1 A convergence of scientific fields including chemistry, biology , physics, optics, and mechanics, nanoscale science and technology operates at the scale of 1-100 nanome-ters where structures, devices, and systems have novel functions and properties because of their size. 2 One area with tremendous promise for h...

This evaluation project accessed visitor interaction with the Materials Wall, part of a set of prototypes based around Nanotechnology created for MSI. The Material Wall consists of nine stations that each detail a different material. At each station there is a short interactive experiment for the visitor to do, brief (one or two sentence) instructions, an image and a short text that describe us...

The development of molecular nanotechnology (MNT) carries numerous risks, including the production of potentially unhealthy nanoparticles, the possible creation of tiny, destructive, self-replicating robots, and many others. The Precautionary Principle is often invoked when dealing with situations that might be hazardous; however, the label "Precautionary Principle" is attached to at least two ...

nanotechnology is an emerging discipline, having power to revolutionarize every scientific field to a very deep level which previously thought to be a science fiction. having a great potential to beneficially change the way a disease is diagnosed, treated and prevented, nanotechnology practically impacts on state of the art healthcare technologies and plays a crucial role in changing the field ...

Nanotechnology is a multidisciplinary field that covers a vast and diverse array of devices and machines derived from engineering, physics, materials science, chemistry and biology. These devices have found applications in biomedical sciences, such as targeted drug delivery, bio-imaging, sensing and diagnosis of pathologies at early stages. In these applications, nano-devices typically interfac...

The picture on the cover page shows a representation of ATP-synthase which is an example of a real molecular motor capable of rotary motion.

Nanotechnology is the engineering of functional systems at the molecular scale which may exert a revolutionary impact on cancer diagnosis and therapy. Nanotechnology is being applied to cancer in two broad areas: i) the development of nanovectors such as nanoparticles which can be loaded with drugs or imaging agents and then targeted to tumours, and ii) high-throughput nanosensor devices for de...
