A new review article appearing in Environmental Health Perspectives focuses on the use of nanomaterials for environmental cleanup. The authors conclude that the technology could be an effective and economically viable alternative for some current site cleanup practices, but potential risks remain poorly understood.

When irradiated with light, gold nanoparticles become hot quickly, hot enough to generate explosive microbubbles that will kill nearby cancer cells, a physical process known as the photothermal effect. To boost this approach, researchers at the University of California, Los Angeles, have developed a method for creating supramolecular assemblies of gold nanoparticles that function as [...]

So-called memristors could replace today’s transistors and lead to a new class of computing devices, Hewlett-Packard scientists say. NYT > Nanotechnology Share and Enjoy:

Standard methods of screening men for prostate cancer leave much to be desired, particularly in terms of their inability to have much effect on prostate cancer survival. Now, a team of investigators at the University of Missouri School of Medicine have created a targeted gold nanoparticle that appears to offer a more sensitive and accurate [...]
