Testing nano materials to build consumer confidence

Engineered nano materials (ENM) are being used more and more in a variety of commercial products. However, there is also concern that some of these properties may be harmful to humans. The FP7-funded research project, NANOSOLUTIONS aims to address this problem by classifying the safety potential of a variety of ENMs.

Watching nanofluids flow in 4D real-time (w/video)

Researchers have applied a new imaging technique called four-dimensional (4D) electron microscopy to the nanofluid dynamics problem. They describe how they visualized and monitored the flow of molten lead within a single zinc oxide nanotube in real time and space.

Shaken, not stirred - Janus capsules please

Janus capsules, miniature, hollow structures, appear in different fragments composed of different micro- and nanoparticles. Theoreticians were able to design models of such capsules, but a real challenge was to produce them. Now, Janus capsules can be produced easily and at low cost.

'Nanosubmarine' delivers complementary molecules inside cells

Researchers created nanoparticles that under the right conditions, self-assemble - trapping complementary guest molecules within their structure. Like tiny submarines, these versatile nanocarriers can navigate in the watery environment surrounding cells and transport their guest molecules through the membrane of living cells to sequentially deliver their cargo.
