How do individual cells or proteins react to changing pH levels? Researchers at the MESA+ Institute for Nanotechnology at the University of Twente have developed a technique for 'gently' adjusting pH: in other words, without damaging biomolecules.
Bei der Aufklaerung der Strukturen von transparenten Festkoerpern sind Physiker einen bedeutenden Schritt vorangekommen. Ein von ihnen entwickeltes, auf der Einzelmolekuelspektroskopie beruhendes Verfahren ist imstande, die Strukturen eines Festkoerpers, z.B. eines polykristallinen Materials, unter dem Mikroskop sichtbar zu machen.
Max Planck Institute for Plasma Physics (IPP) at Garching and the Technical University of Munich (TUM) have concluded an agreement to intensify their collaboration in the field of fusion research. This will entail inauguration of three joint professorships.
Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification.
Scientists at Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage.
Nader Jalili, an associate professor of mechanical and industrial engineering at Northeastern University, is working to create a controlled nanorobot that will be capable of performing non-invasive cancer surgery with a degree of precision not possible through existing surgical procedures.
Researchers have devised a sensor on a chip that can not only detect but also measure single particles. They expect the sensor will be able to measure nanoparticles smaller than 100 nanometers in diameter (about the size of a virus particle) on the fly.
A quick and easy way to take 3D images at the nanoscale with a single measurement has been developed by US researchers. The process works by bouncing a single beam of x-rays off an object, then collecting the scattered wave pattern using a curved detector.
Through the Yousef Jameel Science and Technology Research Center, AUC faculty are conducting cutting-edge research that includes the development of novel diagnostic tests for sensitive detection of the hepatitis C virus; detection of cancer biomarkers, as well as creating a new generation of nano-devices that include smart bricks with tiny sensors, which can analyze building safety and warn of fires and earthquakes.
