Having the ability to measure pH in a tissue without the need for a biopsy could provide clinicians with a rapid method for determining if a suspicious growth is malignant. Two novel nanoparticles raise the distinct possibility that making such measurements could soon be reality.
The August issue of nanoRISK looks at nanotechnology applications in the military; the use of nanoparticles in the cosmetics industry; reports on a new, collaborative approach to nanotoxicology at the National University of Singapore; and numerous briefs on papers, initiatives, upcoming events and new book releases.
Researchers at Pacific Northwest National Laboratory have demonstrated a new, environmentally friendly process for treating water contaminated by perchlorate, a toxic chemical that has been found in drinking water in 35 states.
Bombarding a carbon nanotube with electrons causes it to collapse with such incredible force that it can squeeze out even the hardest of materials, much like a tube of toothpaste, according to an international team of scientists.
Adhesives are supposed to harden quickly and reliably - and connection should be debondable without difficulty once they have done their job. Fraunhofer researchers have developed the first adhesive to reconcile these contradictory requirements.
