Volume 2 Issue 1, January 2007

Editorial

  • Security and surveillance are emerging as major and sometimes controversial applications of nanotechnology, especially in the United States. Although some of these applications are to be welcomed, others should be handled with care.

Commentary

  • Nanotechnology is having a major impact on medicine and the treatment of disease, notably in imaging and targeted drug delivery. It may, however, be possible to go even further and design 'pseudo-cell' nanofactories that work with molecules already in the body to fight disease.

  • The response of a cantilever to bacteria deposited on it depends on the mechanical properties of the sample, as well as its mass. This effect needs to be considered in sensor design.

  • By coating a nanotube with a molecular layer that is thicker on one end than the other, it is possible to make a thermal rectifier that allows heat to flow easily along the tube in one direction, but not so easily in the opposite direction.
