World's smallest nanomotor could power cell-sized nanobots for drug delivery. Scientists at the Cockrell School of Engineering at the University of Texas have built and tested what appears to be the world's smallest, fastest, and longest-running nanomotor yet – so small that it could fit inside a single cell.

The advance could be used to power nanobots that would deliver specific drugs to individual living cells inside the human body. In the distant future, when faced with a cancer diagnosis, we might be able to simply ingest a "magic pill" filled with hordes of miniscule nanobots that target individual cancerous cells with drugs and leave the healthy ones unharmed. New material for flat semiconductors. Researchers around the world have been working to harness the unusual properties of graphene, a two-dimensional sheet of carbon atoms.

New material for flat semiconductors

But graphene lacks one important characteristic that would make it even more useful: a property called a bandgap, which is essential for making devices such as computer chips and solar cells. Now, researchers at MIT and Harvard University have found a two-dimensional material whose properties are very similar to graphene, but with some distinct advantages — including the fact that this material naturally has a usable bandgap. The research, just published online in the Journal of the American Chemical Society, was carried out by MIT assistant professor of chemistry Mircea Dincă and seven co-authors. A glow of recognition. Researchers at MIT have developed a new way of revealing the presence of specific chemicals — whether toxins, disease markers, pathogens or explosives.

A glow of recognition

The system visually signals the presence of a target chemical by emitting a fluorescent glow. The approach combines fluorescent molecules with an open scaffolding called a metal-organic framework (MOF). This structure provides lots of open space for target molecules to occupy, bringing them into close proximity with fluorescent molecules that react to their presence. The findings were reported in the Journal of the American Chemical Society in a paper by assistant professor of chemistry Mircea Dincă, with postdoc Natalia Shustova and undergraduate student Brian McCarthy, published online in November and to appear in a forthcoming print issue.

Synthetic biology gets reborn as an aesthetic dream - 28 April 2014

If synthetic biologists think like scientists, they may miss their eureka moment. Synthetic biology is an emerging discipline, but paradoxically it is not particularly new.

If synthetic biologists think like scientists, they may miss their eureka moment

Since the mid-1970s we have been developing ways of instructing pieces of biology to perform useful tasks in an ever more efficient and sustainable way. Much of this has found its expression in industrial biotechnology, manufacturing things like drugs, enzymes and proteins. It has applications in everything from biofuels to pollution sensors, from smart plastics to cutting-edge medicines. You could conceive of synthetic biology as writing little DNA programs that instruct cell behaviour, like a little genetic app.

UC Riverside Researcher Uses Snail Teeth as Inspiration for More Efficient Solar Cells. A recent study conducted at the University of California has shown how teeth-growing techniques of marine snails can be applied to the solar industry, helping to create improved solar cells and lithium-ion batteries.

The findings show that gumboot chitons – a variety of large marine snails – use conveyer belt-like magnetic teeth to grasp algae on rocks. This biomineralization process could help grow minerals used in solar cells and batteries and also make harder, abrasion and impact-resistant materials. David Kisailus, assistant professor of chemical and environmental engineering at the University of California, Riverside started studying chitons five years ago, with particular focus on its specific teeth-forming process.

The new material could be used to improve the security and lifetime of plastic parts in everyday products such as electrical components, cars and even houses. The researchers have dubbed the material a 'Terminator' polymer in tribute to the shape-shifting, molten T-100 terminator robot from the Terminator 2 film. The research is published in the Royal Society of Chemistry journal Materials Horizons. Self-healing polymers that can spontaneously achieve quantitative healing in the absence of a catalyst have never been reported, until now. The scientists prepared the self-healing thermoset elastomers from common polymeric starting materials using a simple and inexpensive approach. How Flake-Handling Trick Will Enable Graphene's Next Revolution.

In recent months, a new sense of excitement has spread through the graphene research community.

These guys are no longer focused on what they can do with single layers of carbon chickenwire. Instead they have a more ambitious plan. The new goal is to take single layers of high quality graphene and pile them on top of each other to create what physicists call van der Waals heterostructures, layer cakes of carbon crystals each just a single atom thick that promise to behave in entirely new ways. The hope is that this will open the way to undreamt of applications in superconductivity, semiconductor physics and so on. Scientists push and pull droplets with graphene. Scientists at the U.S.

Scientists push and pull droplets with graphene

Naval Research Laboratory (NRL) have moved liquid droplets using long chemical gradients formed on graphene. The change in concentration of either fluorine or oxygen formed using a simple plasma-based process either pushes or pulls droplets of water or nerve agent simulant across the surface. This new achievement offers potential applications ranging from electronics to mechanical resonators to bio/chemical sensors. Secrets of the World's Most Remarkable Natural Materials - Wired Science.

Companies seeking breakthrough products tend to ignore the greatest invention machine in the universe: life’s more than three-billion-year history of evolution by natural selection. What’s missing is a systematic way of capturing nature’s creativity, says Janine Benyus, a biologist, "innovation consultant" and author. Engineering practices are fractured, Benyus says. Experts in biomimetics study materials; bionics engineers work on prostheses and mechanics.

New high-tech laser method allows DNA to be inserted 'gently' into living cells. ( —The applications of gene therapy and genetic engineering are broad: everything from pet fish that glow red to increased crop yields worldwide to cures for many of the diseases that plague humankind. But realizing them always starts with solving the same basic scientific question—how to "transfect" a cell by inserting foreign DNA into it.

Many methods already exist for doing this, but they tend to be clumsy and destructive, not allowing researchers to precisely control how and when they insert the DNA or requiring them to burn through large numbers of cells before they can get it into one. A team of scientists in South Korea have now developed the most precise method ever used to insert DNA into cells. New high-tech laser method allows DNA to be inserted 'gently' into living cells.

Arguably the world’s most famous painting, da Vinci's Mona Lisa has now been copied onto the world’s smallest canvas at the Georgia Institute of Technology. Associate Professor Jennifer Curtis' "Mini Lisa" is one-third the width of a human hair, with details as small as one-eighth of a micron.

Mini Lisa demonstrates the flexibility of a new nanolithography technique that can vary the surface concentration of molecules on very small portions of a substrate. View all Mini Lisa was rendered using an atomic force microscope and a new process called ThermoChemical NanoLithography (TCNL). The Georgia Tech team formed the image pixel by pixel. The molecular canvas is a plastic whose surface contains active chemical sites which are initially protected from chemical reaction by capping them with protecting molecules.

Cancer cell illustration courtesy of iStockphoto/Eraxion Chemotherapy treatment for cancer is a nasty process. Doctors must try to give patients just enough of the toxic drugs to kill off cancer cells without doing too much harm to the rest of the body’s healthy tissues, a balancing act that, even if successful, can nevertheless cause horrible side effects.
