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.
Researchers have developed a manufacturing process for nanocellulose powder, the raw material for creating polymer composites which can be used, for example, in lightweight structures for the car industry or as membrane and filter material for biomedicinal applications.
If quantum computers are ever to be realized, they likely will be made of different types of parts that will need to share information with one another, just like the memory and logic circuits in today's computers do. However, prospects for achieving this kind of communication seemed distant - until now. A team of physicists has shown for the first time how these parts might communicate effectively.
Recent work offers a way to measure accurately both the distribution of cluster sizes in a sample and the characteristic light absorption for each size. The latter is important for the application of nanoparticles in biosensors.
