Combining 3-D Printing with Nanofiber Spinning Technique May Help Create Better Artificial Cartilage

In a significant step toward reducing the heavy toll of osteoarthritis around the world, scientists have created the first example of living human cartilage grown on a laboratory chip. The researchers ultimately aim to use their innovative 3-D printing approach to create replacement cartilage for patients with osteoarthritis or soldiers with battlefield injuries.

ETH Researchers Use Nanotechnology and DNA to Protect Olive Oil from Counterfeiters

Just a few grams of the new substance are enough to tag the entire olive oil production of Italy. If counterfeiting were suspected, the particles added at the place of origin could be extracted from the oil and analysed, enabling a definitive identification of the producer. "The method is equivalent to a label that cannot be removed," says Robert Grass, lecturer in the Department of Chemistry and Applied Biosciences at ETH Zurich.

Researchers Build DNA Nanodevices that Survive Body's Immune Mechanism

It's a familiar trope in science fiction: In enemy territory, activate your cloaking device. And real-world viruses use similar tactics to make themselves invisible to the immune system. Now scientists at Harvard's Wyss Institute for Biologically Inspired Engineering have mimicked these viral tactics to build the first DNA nanodevices that survive the body's immune defenses.

Gold Nanoparticle Array Fabricated Onto Hybrid Live Cell-Supported Membrane Using Size-Based Chromatography

Using nanodot technology, Berkeley Lab researchers have demonstrated the first size-based form of chromatography that can be used to study the membranes of living cells. This unique physical approach to probing cellular membrane structures can reveal information critical to whether a cell lives or dies, remains normal or turns cancerous, that can’t be obtained through conventional microscopy.

New Type of Nanocrystalline Cellulose Helps Prevent Spread of Virus into Cells

There are many viral diseases in the world for which no pharmaceutical treatment exists. These include, among others, dengue fever, which is spread by mosquitoes in the tropics, as well as a type of diarrhea, which is more familiar in Finland and is easily spread by the hands and can be dangerous especially for small children and the elderly.

Novel Nanosensors Help Track ABA Stress Hormones in Plants

Biologists at UC San Diego have succeeded in visualizing the movement within plants of a key hormone responsible for growth and resistance to drought. The achievement will allow researchers to conduct further studies to determine how the hormone helps plants respond to drought and other environmental stresses driven by the continuing increase in the atmosphere’s carbon dioxide, or CO2, concentration.
