Scienists have investigated theoretically the mechanism of hyperthermic potentiation of cancers using magnetic nanoparticles, which enables selective heating of hidden micro cancer tissue, and clarified the fact that the nanoparticles under large magnetic fields form unique oriented states, depending respectively on subtle differences in their local environment in the cancer tissue and consequently affect the optimum heating conditions.
Imagine if the next coat of paint you put on the outside of your home generates electricity from light-electricity that can be used to power the appliances and equipment on the inside. A team of researchers at the University of Notre Dame has made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy.
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.
