Flares on the move: Nanoparticle test kit shows how nanoparticles of different size disperse in tumor tissue

Nanoparticles play a significant role in the development of future diagnostic and therapeutic techniques for tumors, for example as transporters for drugs or as contrast agents. Absorption and dispersion of nanoparticles in tumor tissue depend strongly on particle size. In order to systematically study this, scientists at the Massachusetts Institute of Technology and Harvard Medical School have now produced a set of fluorescent nanoparticles of various diameters between 10 and 150 nm.

Virus killer gets supercharged with nanoparticles

A simple technique to make a common virus-killing material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li. Rather than trying to turn the process into profit, the researchers have put it into the public domain.

Coiled nanowires may hold key to stretchable electronics

Researchers at North Carolina State University have created the first coils of silicon nanowire on a substrate that can be stretched to more than double their original length, moving us closer to incorporating stretchable electronic devices into clothing, implantable health-monitoring devices, and a host of other applications.

Polymer membranes with molecular-sized channels that assemble themselves

Many futurists envision a world in which polymer membranes with molecular-sized channels are used to capture carbon, produce solar-based fuels, or desalinate sea water, among many other functions. This will require methods by which such membranes can be readily fabricated in bulk quantities. A technique representing a significant first step down that road has now been successfully demonstrated.

Trapped sunlight cleans water

A ew system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source, sunlight. Microfluidics - transporting water through tiny channels - and photocatalysis - using light to break down impurities - come together in the science of optofluidics.

Debunking solar energy efficiency measurements

In recent years, developers have been investigating light-harvesting thin film solar panels made from nanotechnology - and promoting efficiency metrics to make the technology marketable. Now a Tel Aviv University researcher is providing new evidence to challenge recent charge measurements for increasing solar panel efficiency.
