Researchers have overcome this problem by an elegant self-assembly technique that produces millions of nanolenses on the basis of metallic nanoparticles in combination with DNA structures. These nanolenses enable 100fold more sensitive detection of even single molecules than previous approaches.
Wissenschaftler an der Technischen Universität Braunschweig, hat nun ein Verfahren entwickelt, bei dem Millionen sogenannter Nanolinsen aus metallischen Nanoteilchen und DNA parallel hergestellt werden. Diese Nanolinsen erlauben es, sogar einzelne Moleküle bis zu einhundertfach genauer zu untersuchen.
The study of materials at extreme conditions took a giant leap forward with the discovery of a way to generate super high pressures without using shock waves whose accompanying heat turns solids to liquid.
A team of UC Davis scientists has shown in experimental mouse models that a new drug delivery system allows for administration of three times the maximum tolerated dose of a standard drug therapy for advanced bladder cancer, leading to more effective cancer control without increasing toxicity.
The European Environmental Bureau has joined together with a broad coalition of environmental non-governmental organizations (NGOs), consumer organizations and trade unions to express grave concerns about the conclusions of the second regulatory review of nanomaterials, published by the European Commission on October 3rd.
Scientists in the Advanced Materials and Nanosystems directorate at the Lockheed Martin Space Systems Advanced Technology Center (ATC) in Palo Alto have developed a revolutionary nanotechnology copper-based electrical interconnect material, or solder, that can be processed around 200 C.
Sponsored by the Nanodermatology Society, this art contest is designed to highlight original work of an artistic nature related to nanotechnology and especially nanotechnology in dermatology. Subject matter can include experimental apparatus, models, simulations, nanomaterials rendered in computer graphics, drawings, 3D art, or video.
Researchers from the NIST Center for Nanoscale Science and Technology have developed on-chip optomechanical sensors for atomic force microscopy (AFM) that extend the range of mechanical properties found in commercial AFM cantilevers, potentially enabling the use of this technology to study a wide variety of physical systems.
A University of Southampton team have discovered that by embossing tiny raised or indented patterns onto gold's surface they can change the way it absorbs and reflects light - ensuring our eyes don't see it as golden in color at all.
