European Physical Journal E
Elucidating optimal biological tissue shape during growth
A team of European scientists has now extended a previous biophysical model to investigate elongated growth within biological tissues by describing the evolution over time of the shape of a fruit fly's wing. They found the aspect ratio of the typical biological shapes may exhibit a maximum at finite time and then decrease. The findings have been published in EPJ E.

Chemical sensor on a chip
Scientists at the Vienna University of Technology have managed to create a tiny laser and a corresponding light detector in one production process, on a single chip. The light is transported from the laser to the detector on a specially designed waveguide. That way, the chip can measure the chemical composition of the liquid in which it is submerged.

DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists have used DNA-linked nanoparticles to form a single-particle-thick layer on a liquid surface where the properties of the layer can be easily switched. Understanding the assembly of such nanostructured thin films provides a possible pathway to adjustable filters, surfaces with variable mechanical response, or even new ways to deliver genes for biomedical applications.

Technology using microwave heating may impact electronics manufacture
Engineers have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating -- essentially the same forces that heat up leftover food with such efficiency. This may finally make it possible for this technology to move into large scale manufacturing and usher in an electronics revolution.

Penn research develops 'onion' vesicles for drug delivery
University of Pennsylvania researchers have shown that a certain kind of dendrimer, a molecule that features tree-like branches, offers a simple way of creating vesicles and tailoring their diameter and thickness. Moreover, these dendrimer-based vesicles self-assemble with concentric layers of membranes, much like an onion.

Princeton Plasma Lab funded to explore nanoparticles with plasma
The US Department of Energy's Princeton Plasma Physics Laboratory has received some $4.3 million of DOE Office of Science funding, over three years, to develop an increased understanding of the role of plasma in the synthesis of nanoparticles. Such particles, which are measured in billionths of a meter, are prized for their use in everything from golf clubs and swimwear to microchips, paints and pharmaceutical products. They also have potentially wide-ranging applications in the development of new energy technologies.

New class of nanoparticle brings cheaper, lighter solar cells outdoors
Researchers in the University of Toronto's Edward S. Rogers Sr. Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that outshines the current state of the art employing this new class of technology. This new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots, could lead to cheaper and more flexible solar cells, as well as better gas sensors, infrared lasers, infrared light emitting diodes and more.

Opening a wide window on the nano-world of surface catalysis
A surface catalyst with a built-in sensor: that's what University of South Carolina chemist Hui Wang and co-workers built by bridging a size gap on the nano-scale. Their silver nanoparticles combine plasmon resonance with catalytic activity, making SERS and other analytical data available in real time on a surface catalyst.

Design of self-assembling protein nanomachines starts to click
Biological systems produce an incredible array of self-assembling protein tools on a nanoscale, such as molecular motors, delivery capsules and injection devices. Inspired by sophisticated molecular machines naturally found in living things, scientists want to build their own with forms and functions customized to tackle modern day challenges. A new computational method, proven to accurately design protein nanomaterials that arrange themselves into a symmetrical, cage-like structure, may be an important step toward that goal.

Speeding food safety tests to deliver fresher products
New techniques designed by Nugen and fellow food scientists Amanda Kinchla and doctoral student Juhong Chen, with nanochemist Vincent Rotello, should help food manufacturers avoid costly waiting for safety tests before products can be sold. Food companies may soon need to prove that their products are safe before they ship, since the Food Safety Modernization Act of 2011 shifted the Food and Drug Administration's focus from responding to food contamination to preventing it.
