Nanoparticle exposures happen, says expert
Some nanotechnology fanciers suggest that, like proverbial birds of a feather, engineered nanoscale materials will flock - or clump - together. This tendency, they maintain, should reduce or eliminate risks as nanotechnology manufacturing increases and the number of nanotechnology-enabled products grows. view more (2007-10-12)
Studying component parts of living cells with carbon nanotube cellular probes
Carbon nanotubes (CNTs) have shown great potential for use as cellular probes. As "nanopipes" they can be used to transport liquids to or from cells and inject solutions or drugs directly into individual cells and individual organelles within the cells. view more (2007-10-05)
Clemson physicist addresses international forum on thermoelectric energy

Poll reveals public awareness of nanotech stuck at low level
National survey findings released today indicate that Americans' awareness of nanotechnology remains low. Popular awareness is nearly as small as the tiny nanoscale materials and nano-enabled devices and products now flowing onto the market from this rapidly progressing technology that experts believe will usher in a new industrial revolution. view more (2007-09-25)
Bone-Growing Nanomaterial Could Improve Orthopaedic Implants
For orthopaedic implants to be successful, bone must meld to the metal that these artificial hips, knees and shoulders are made of. A team of Brown University engineers, led by Thomas Webster, has discovered a new material that could significantly increase this success rate. view more (2007-09-18)
Federal research plan to determine nanotech risks fails to deliver
Almost a year in the making, a federal plan to prioritize research on the potential environmental, health, and safety (EHS) impacts of nanoscale materials has so many failings that its begs the question as to whether the government's 13-agency nanotechnology research effort is able to deliver an effective risk research strategy. view more (2007-09-14)
