A new approach to growing graphene greatly reduces problems that have plagued researchers in the past and clears a path to the crystalline form of graphite's use in sophisticated electronic devices of tomorrow.
The easiest and most natural way of penetrating a cell membrane with a carbon nanotube, in its simplest form, is at an angle which is almost flat against the membrane surface, according to a team of Italian researchers. Just as a nurse does to find a vein.
Using a technique known as thermochemical nanolithography (TCNL), researchers have developed a new way to fabricate nanometer-scale ferroelectric structures directly on flexible plastic substrates that would be unable to withstand the processing temperatures normally required to create such nanostructures.
Eine neue Mikroskop-Technologie soll beim Kampf gegen Infektionskrankheiten, Altersdemenz und Krebs helfen. Die Methode heisst Fluoreszenz-Superaufloesungs-Mikroskopie, macht selbst kleinste Biomolekuele sichtbar und liefert so ganz neue Bilder aus lebenden Zellen: live, in 3D und hoch praezise.
Using nanotechnology to engineer sensors onto the surface of cells, researchers at Brigham and Women's Hospital (BWH) have developed a platform technology for monitoring single-cell interactions in real-time.
Olivier Pfister, a professor of physics in the University of Virginia's College of Arts and Sciences, has just published findings demonstrating a breakthrough in the creation of massive numbers of entangled qubits, more precisely a multilevel variant thereof called Qmodes.
A team of researchers from MIT, the Sanford-Burnham Medical Research Institute, and the University of California at San Diego (UCSD) has designed a new type of delivery system in which a first wave of nanoparticles hones in on the tumor, then calls in a much larger second wave that dispenses the cancer drug. This communication between nanoparticles, enabled by the body's own biochemistry, boosted drug delivery to tumors by more than 40-fold in a mouse study.
Head and neck cancer, the sixth most common cancer in the world, has remained one of the more difficult malignancies to treat, and even when treatment is successful, patients suffer severely from the available therapies. Now, researchers at the University of Michigan have developed a tumor-targeted nanoparticle that delivers high doses of anticancer agents directly to head and neck tumors.
Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, enabling the resulting nanoparticles to evade the body's immune system and deliver cancer-fighting drugs straight to a tumor.
A combination of two ordinary materials - graphite and water - could produce energy storage systems that perform on par with lithium ion batteries, but recharge in a matter of seconds and have an almost indefinite lifespan.
Researchers demonstrated how semiconductor nanocrystals can be doped in order to change their electronic properties and be used as conductors. This opens a world of possibilities in terms of applications of small electronic and electro-optical devices, such as diodes and photodiodes, electric components used in cellular phones, digital cameras, and solar panels.
Implants that obtain their energy from blood sugar and oxygen: Dr. Sven Kerzenmacher at the Department of Microsystems Engineering (IMTEK) of the University of Freiburg is researching the development of biological fuel cells with the goal of finding an inexhaustible source of power in the human body.
