A variety of nanoparticles have shown to be effective in delivering cancer drugs more directly to tumor cells, mitigating the damage to nearby healthy cells. Now, researchers from Purdue University have demonstrated that these nanoparticles are getting their drug payloads to the correct intracellular compartments.
Single-walled carbon nanotubes have been highly touted for their potential as novel delivery agents for cancer detection and therapeutic agents. Now, a team of investigators from six institutions have created a multifunctional carbon nanotube that can detect and destroy an aggressive form of breast cancer.
Just as fly paper captures insects, a pair of nanotechnology-enabled devices are able to grab cancer cells in the blood that have broken off from a tumor. These cells, known as circulating tumor cells, or CTCs, can provide critical information for examining and diagnosing cancer metastasis, determining patient prognosis, and monitoring the effectiveness of therapies.
A team of researchers from two of the National Cancer Institute's Centers of Cancer Nanotechnology Excellence have teamed up to develop a 'cocktail' of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors.
MediSens Wireless, a startup company in UCLA's on-campus technology incubator at the California NanoSystems Institute, has obtained approval under federal Food and Drug Administration guidelines to begin clinical trials on its novel wireless body-monitoring system, which assesses muscle and neuromotor functions in the upper extremities.
When ribosomes produce protein in all living cells, they do so through a chemical reaction that happens so fast that scientists have been puzzled. Using large quantum mechanical calculations of the reaction center of the ribosome, researchers at Uppsala University in Sweden can now provide the first detailed picture of the reaction.
Metamaterialien haben besondere optische Eigenschaften: Zum Beispiel brechen sie Licht in eine andere Richtung als alle natuerlichen Materialien, sie haben also einen negativen Brechungsindex. Mit dem EU-Projekt NIM_NIL wollen Wissenschaftler des ISAS solche Metamaterialien fuer sichtbares Licht herstellen.
Scientists at the National Institute of Standards and Technology (NIST) and Indiana University (IU) have determined the most accurate values ever for a fundamental property of the element lithium using a novel approach that may permit scientists to do the same for other atoms in the periodic table.
A research team at the National Institute of Standards and Technology (NIST) has quantified the interaction of gold nanoparticles with important proteins found in human blood, an approach that should be useful in the development of nanoparticle-based medical therapies and for better understanding the physical origin of the toxicity of certain nanoparticles.
