Stir this clear liquid in a glass vial and nothing happens. Shake this liquid, and free-floating sheets of protein-like structures emerge, ready to detect molecules or catalyze a reaction. This isn't the latest gadget from James Bond's arsenal -- rather, the latest research from the Berkeley Lab scientists unveiling how slim sheets of protein-like structures self-assemble.
A group of researchers has devised a unique experiment to mimic the natural process of biomineralization in order to create oriented gold nanocrystals and examine their formation at the U.S. Department of Energy Office of Science's Advanced Photon Source (APS) at Argonne National Laboratory.
Scientists report what they believe is the first pre-clinical demonstration of the potential of molecularly targeted nanoparticles as a promising new class of agents that can improve chemoradiotherapy treatment.
Dopamine deficiency is indicative of serious diseases of the nervous system. Tests of dopamine concentration are expensive and require specialised equipment that is unavailable in doctors' offices. New electrodes coated with carbon nanoparticles deposited on silicate submicroparticles allow to detect dopamine in solutions easily and at low cost, even in the presence of interferences.
A new center at UC Santa Barbara has the development of an artificial pancreas in its sights, as well as new biomaterials, new tools for the detection and diagnosis of disease, and new mechanisms for drug delivery -- among other cutting-edge scientific developments.
Das BfR hatte zu einem Workshop ueber Nanopartikel in Verbraucherprodukten eingeladen, um bestehende Risiken und moegliche Handlungsoptionen fuer einen umfassenden Schutz der Verbraucherinnen und Verbraucher zu diskutieren.
