Rochester expert warns of toxicity in new wave of science
Nanotechnology, a science devoted to engineering things that are unimaginably small, may pose a health hazard and should be investigated further, warns a University of Rochester scientist and worldwide expert in the field, who received a $5.5 million grant to conduct such research.
Günter Oberdörster, Ph.D., professor of Toxicology in Environmental Medicine and director of the universitys EPA Particulate Matter Center, has already completed one study showing that inhaled nano-sized particles accumulate in the nasal cavities, lungs and brains of rats. Scientists speculate this buildup could lead to harmful inflammation and the risk of brain damage or central nervous system disorders. Oberdörsters study is scheduled to appear in the May 2004 journal Inhalation Toxicology, and is receiving widespread attention in the scientific community; it was cited at an international nanotechnology/health conference earlier this year in England by the Institute of Physics.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
