Stomach acid-powered micromotors get their first test in a living animal
Researchers at the University of California, San Diego have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the width of a human hair, may someday offer a safer and more efficient way to deliver drugs or diagnose tumors. The experiment is the first to show that these micromotors can operate safely in a living animal.

Carbon nanoballs can greatly contribute to sustainable energy supply
Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 percent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

Engineering self-assembling amyloid fibers
Nature has many examples of self-assembly, and bioengineers are interested in copying these systems to create useful new materials or devices. Amyloid proteins, for example, can self-assemble into the tangled plaques associated with Alzheimer's disease -- but can also form very useful materials, such as spider silk, or biofilms around living cells. Researchers at UC Davis and Rice University have now come up with methods to manipulate natural proteins so that they self-assemble into amyloid fibrils.

Nanoshuttle wear and tear: It's the mileage, not the age
As nanomachine design advances, researchers are moving from wondering if the nanomachine works to how long it will work -- an important question as there are so many potential applications, e.g., for medical uses including drug delivery and early diagnosis. Columbia Engineering Professor Henry Hess observed a molecular shuttle powered by kinesin motor proteins and found it to degrade when operating, marking the first time degradation has been studied in detail in an active, autonomous nanomachine.

New technique helps probe performance of organic solar cell materials
Researchers have developed a technique for determining the role that a material's structure has on the efficiency of organic solar cells, which are candidates for low-cost, next generation solar power. The researchers used the technique to determine that materials with a highly organized structure at the nanoscale are not more efficient at creating free electrons than poorly organized structures -- a finding which will guide future research and development efforts.

Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered 'elastic' waves. These waves travel at the surface or through a material without causing any permanent changes to the substance's makeup. Now, engineering researchers at the University of Missouri have developed a material that has the ability to control these waves, creating possible medical, military and commercial applications with the potential to greatly benefit society.

What is the current development in nanomedicine for clinical diagnosis and treatment?
Nanomedicine has been advancing rapidly, particularly in the development of novel nano tools for medicine. This requires multiple nano functionalities for cell targeting, drug storage, optical imaging, and effective treatment. 'Bio-inspired Nanomaterials and Devices' summarizes the most recent developments in nanomaterials, biotechnology, and medical diagnosis and therapy for researchers from diverse fields of chemistry, materials science, physics, engineering, biology, and medicine. Not only does the book touch up on the most fundamental topics, but also deal with critical clinical issues.

Graphene enables all-electrical control of energy flow from light emitters
Scientists from the Institute of Photonic Science, the Massachusetts Institute of Technology, Centre National de la Recherche Scientifique, Consorzio Nazionale Italiano di Struttura della Materia and Graphenea have now demonstrated active, in situ electrical control of the energy flow from erbium ions into photons and plasmons. The experiment was implemented by placing the erbium emitters a few tens of nanometers away from the graphene sheet, whose carrier density is electrically controlled. Partially funded by the EC Graphene Flagship, this study entitled 'Electrical control of optical emitter relaxation pathways enabled by graphene,' has been published in Nature Physics.

Wearable sensor clears path to long-term EKG, EMG monitoring
Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiographyor electromyography. The new sensor is as accurate as the 'wet electrode' sensors used in hospitals, but can be used for long-term monitoring and is more accurate than existing sensors when a patient is moving.
