Bacteria use various appendages to move across surfaces prior to forming multicellular bacterial biofilms. Some species display a particularly jerky form of movement known as "twitching" motility, which is made possible by hairlike structures on their surface called type IV pili, or TFP.
Researchers from A*STAR Institute of Microelectronics (IME) have developed a lateral silicon-based drug screening tool that has demonstrated simultaneous capture of 12 individual cells - 12 times higher throughput than conventional patch clamping.
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.
