The discovery of unexpected magnetic interactions between ultrasmall specks of rust is leading scientists at Rice University’s Center for Biological and Environmental Nanotechnology (CBEN) to develop a revolutionary, low-cost technology for cleaning arsenic from drinking water. The technology holds promise for millions of people in India, Bangladesh and other developing countries where thousands of cases of arsenic poisoning each year are linked to poisoned wells.

New optics research from Rice University's Laboratory for Nanophotonics suggests that tiny gold particles called nanostars could become powerful chemical sensors.

Materials on the nanoscale don’t always have the same properties they would in bulk; for one thing, nanomaterials are often a lot harder. Unlike most bulk materials, a crystal that is small enough can be perfect, free of defects, capable of achieving strength near its ideal theoretical limit.

Scientists from the US Department Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a ruler made of gold nanoparticles and DNA that can measure the smallest of life’s phenomena, such as precisely where on a DNA strand a protein attaches itself.

The world’s first machine to simultaneously measure two vital properties of airborne nanoparticle pollution is going on an overseas trip to a leading atmospheric chemistry laboratory in Switzerland. The analyser, developed by the Queensland University of Technology’s International Laboratory for Air Quality and Health, measures the volatile and hygroscopic (water absorbing) properties of nanoparticles emitted from vehicles.
