Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and without need for refrigeration. The tiny needles can be fabricated under normal temperature and pressure and from water, so they can be loaded with sensitive biochemical compounds and maintain their activity prior to use. They are also biodegradable and biocompatible.
This document provides a snapshot of information on national activities on the life cycle assessment of nanotechnologies provided by OECD countries. As a "living document", it is expected to be updated as new information becomes available.
This document presents lessons learned from information gathering surveys carried out by OECD countries and summarises non-confidential business information and statistics on nanomaterials. It includes useful information on how to design/implement information gathering surveys and the most commonly used nanomaterials along with use patterns and volumes used among OECD countries.
A technique for real-time monitoring of the galvanic replacement reaction between silver nanowires and aqueous gold salt solutions using in situ flow-cell transmission X-ray microscopy (TXM) has been developed by scientists in the Center for Nanoscale Materials Nanophotonics Group and the Advanced Photon Source X-Ray Science Division at Argonne.
Concerned by the growing body of scientific reports cautioning against the unregulated use of nanotechnology in consumer products, a coalition of nonprofit consumer safety and environmental groups sued the Food and Drug Administration (FDA) today. The case is the first lawsuit over the health and environmental risks of nanotechnology and nanomaterials.
Researchers have developed gold plasmonic nanocrosses that are particularly suited to eliminating cancer cells in cancer therapy. The team demonstrated the usefulness of these nanocrosses by using them to kill human lung cancer cells.
Catalysts are one of those things that few people think much about, beyond perhaps in high school chemistry, but they make the world tick. Almost everything in your daily life depends on catalysts: cars, Post-It notes, laundry detergent, beer.
An international research team headed by DESY scientists from the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany, has recorded the shortest X-ray exposure of a protein crystal ever achieved. The incredible brief exposure time of 0.000 000 000 000 03 seconds (30 femtoseconds) opens up new possibilities for imaging molecular processes with X-rays.
