Nanotechnology

The very same building blocks that make us have been successfully programmed to form 32 differently-shaped crystal structures. The structures feature a precisely-defined depth and a variety of sophisticated 3D nanoscale attributes, thereby laying further foundations for the use of DNA to revolutionize nanotechnology.

Many of us drink green tea for its wonderful health benefits, including proven antioxidant, antimicrobial, anti-aging and anti-cancer properties. Now, researchers in Singapore have taken its cancer-fighting properties to the next level, developing a green tea-based nanocarrier that encapsulates cancer-killing drugs. It is the first time green tea has been used to deliver drugs to cancer cells, with promising results. Animal studies show far more effective tumor reduction than use of the drug alone while significantly reducing the accumulation of drugs in other organs. Read More
With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent. Read More
Clingy barnacles might be something of a nuisance for seafarers, but these stubborn shellfish and their relatives could hold the key to a new breed of sticky materials. Engineers from MIT have created waterproof adhesives based on the proteins that give these creatures such qualities, a development that could one day be used in ship repairs or medical applications.

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity in only the one direction. In essence, a rectifier diode, but one so small that it may one day help replace much bulkier diodes and other semiconductors found on today's integrated circuits to produce incredibly compact, super-fast electronic devices.

The search for more efficient tests of pharmaceuticals without animal models is taking a stride forward, with a new technology being developed in the US called Organs-on-Chips. The new miniature platform and software, which mimic the mechanical and molecular characteristics of human organs, were developed by bioengineers from the Wyss Institute for Biologically Inspired Engineering at Harvard University.

What if your house's windows could automatically reduce the amount of hot sunlight passing through them, or your car's windshield could cause rain droplets to bead off to its edges? These things and more could soon be possible, thanks to a new animal hair-inspired material developed at MIT. Read More
Stanford University researchers claim to have created the first stable pure lithium anode in a working battery by using carbon nanospheres as a protective sheath to guard against degradation. As a result, the researchers predict that commercial developments may eventually result in anything up to a quadrupling of battery life in the not-too-distant future. Read More
A newly produced material is believed to be the "blackest" ever created. Vantablack is a pure carbon coating and absorbs 99.96 percent of incident radiation (solar energy as it hits the material's surface). Manufacturer Surrey NanoSystems believes that is the highest such figure ever recorded. Read More
For residents living in the north, where sunlight can be a rare commodity during the winter, a psychological condition known as Seasonal Affective Disorder is a very real problem. Light therapy is one way to shake off the winter blues, and although artificial lighting solutions do exist, they are generally available as simple variations on traditional desk lamps. An Italian designer has developed CoeLux, a unique system that delivers artificial light through an intelligent false skylight. Read More
