Sean Nealon, University of California, Riverside Material that could change electronics industry is shown to be very mobile in water and likely to cause negative environmental impacts if spilled In a first-of-its-kind study of how a material some think could transform the electronics industry moves in water, researchers at the University of California, Riverside Bourns College of Engineering found graphene oxide nanoparticles are very mobile in lakes or streams and therefore likely to...

Using magnetically controlled nanoparticles to force tumor cells to 'self-destruct' sounds like science fiction, but could be a future part of cancer treatment, according to research from Lund University in Sweden. "The clever thing about the technique is that we can target selected cells without harming surrounding tissue. There are many ways to kill cells, but this method is contained and remote-controlled", said Professor Erik Renström. The point of the new technique is that it is...

DOE/Brookhaven National Laboratory Standardized technique opens remarkable opportunities for 'mix and match' materials fabrication Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The technique, described in a paper published online by Nature Nanotechnology on October 20, 2013, opens many opportunities for mixing and matching particles...

Using nanoparticles and alternating magnetic fields, University of Georgia scientists have found that head and neck cancerous tumor cells in mice can be killed in half an hour without harming healthy cells. The findings, published recently in the journal Theranostics, mark the first time to the researchers' knowledge this cancer type has been treated using magnetic iron oxide nanoparticle-induced hyperthermia, or above-normal body temperatures, in laboratory mice. "We show that we can...

Researchers from North Carolina State University have investigated the viability of a technique called "spincasting" for creating thin films of nanoparticles on an underlying substrate "“ an important step in the creation of materials with a variety of uses, from optics to electronics. Spincasting, which utilizes centrifugal force to distribute a liquid onto a solid substrate, already has a variety of uses. For example, it is used in the electronics industry to deposit organic thin...

The next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometers across, can be used to trap antibodies to the virus that causes cervical cancer and to the bacteria that causes potentially lethal diarrhea. According to scientists in Vietnam, it is relatively straightforward to immobilize on nanoparticles, synthetic or monoclonal antibodies...

Blood poisoning can be fatal. If you suffer from sepsis, you used to have to wait as much as 48 hours for laboratory findings. A new diagnostic platform as big as a credit card will now supply the analysis after as little as an hour. This system is based on nanoparticles that are automatically guided by magnetic forces. Although it is the third most frequent cause of death in Germany, blood poisoning is frequently underestimated. In this country, 60,000 persons die every year from some form...

(Ivanhoe Newswire) -- Magnetic fluid hyperthermia (MFH) is a promising new cancer treatment that basically "fries" cells inside tumors. The procedure has been used successfully in prostate, liver, and breast tumors. Magnetic nanoparticles (each billionths of a meter in size) are injected into the body intravenously and diffuse selectively into cancerous tissues. Add a high-frequency magnetic field, and the particles heat up, raising the temperature of the tumor cells. "The entire tumor volume...
