"Electronic modulation of biochemical signal generation" published in Nature Nanotechnology COLLEGE PARK, Md., July 30, 2014 /PRNewswire-USNewswire/ -- Researchers often use microelectronic devices embedded with biological components to interrogate biology, but such devices can do much more - perhaps even control biology. As such, researchers have looked to patterned assemblies of proteins and cells for in vitro metabolic engineering to characterize - and potentially control - cell...

Some three billion base pairs make up the human genome—the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights relevant to human health and disease. Nevertheless, the primary actors in virtually all life processes are the proteins coded for by DNA sequences known as genes. For a broad spectrum of diseases, proteins can yield far more compelling revelations than may be gleaned...

Tufts University engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers. Nanofabrication is at the heart of manufacture of semi-conductors and other electronic and...

The energy needed to change the magnetic orientation of a single atom – which determines its magnetic stability and therefore its usefulness in a variety of future device applications – can be modified by varying the atom's electrical coupling to nearby metals. This striking result was published today in the journal Nature Nanotechnology by an international group of scientists working at the London Centre for Nanotechnology (LCN) at UCL (UK), the Iberian Nanotechnology Laboratory...

Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous cells. "Nitric oxide has contradictory roles in cancer progression, and we need new tools in order to better understand it," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT....

A microfluidic chip developed at the University of Michigan is among the best at capturing elusive circulating tumor cells from blood—and it can support the cells' growth for further analysis. The device, believed to be the first to pair these functions, uses the advanced electronics material graphene oxide. In clinics, such a device could one day help doctors diagnose cancers, give more accurate prognoses and test treatment options on cultured cells without subjecting patients to...

Advanced Ink-jet Technology Prints Nanostructures With Self-assembling Material

The University of Chicago A multi-institutional team of engineers has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. This approach combines top-down advanced ink-jet printing technology with a bottom-up approach that involves self-assembling block copolymers, a type of material that can spontaneously form ultrafine structures. The team, consisting of nine researchers from the University of Illinois at...

Nano and laser technology packed into small device tests antibiotic treatment in minutes Researchers at EPFL have built a matchbox-sized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks. A nano-lever vibrates in the presence of bacterial activity, while a laser reads the vibration and translates it into an electrical signal that can be easily read—the absence of a signal signifies the absence of bacteria. Thanks to...

Nobody knows the remarkable properties of human skin like the researchers struggling to emulate it. Not only is our skin sensitive, sending the brain precise information about pressure and temperature, but it also heals efficiently to preserve a protective barrier against the world. Combining these two features in a single synthetic material presented an exciting challenge for Stanford Chemical Engineering Professor Zhenan Bao and her team. Now, they have succeeded in making the first...

Researchers from the University of Toronto and King Abdullah University of Science & Technology have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever Researchers from the University of Toronto (U of T) and King Abdullah University of Science & Technology (KAUST) have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever. Their work...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
