Nano-technology and nano-toxicology

Nano-technology and nano-toxicology

Rapid developments in nano-technology are likely to confer significant benefits on mankind. But, as with perhaps all new technologies, these benefits are likely to be accompanied by risks, perhaps by new risks. Nano-toxicology is developing in parallel with nano-technology and seeks to define the hazards and risks associated with nano-materials: only when risks have been identified they can be ...

Nano Technology

We present a new approach using genetic algorithms, neural networks, and nano robotics concepts applied to the problem of control design for nanoassembly automation and its application in medicine. As a practical approach to validate the proposed design, we have elaborated and simulated a virtual Environment focused on control automation for nano robotics teams that exhibit collective behavior....

Nano-technology: a Disruptive Technology?

Terahertz Technology for Nano Applications

The terahertz (THz) region of the electromagnetic spectrum is generally defined as the frequency range of 0.1–10 THz (10 cycles per second) corresponding to quantum energy of 0.4 meV–0.4 eV (see Fig. 1). THz electromagnetic waves (also known as T-rays) have several properties that could promote their use as sensing and imaging tool. There is no ionization hazard for biological tissue and Raylei...

Nano - technology : plus ça change . . . ?

This book is a collection of existing articles together with several original contributions that “add to a slowly accumulating literature on Nanotechnology (NT) within the Science Technology and Society field”. That literature in turn reflects an emerging wave of NT products. All this is happening some 50 years after Richard Feynman’s famous speech at Caltech: “There’s plenty of room at the bot...
