Raman nanoparticle-aided imaging of tumors moves closer to human trials

In 2008, a team of investigators at Stanford University's Center for Cancer Nanotechnology Excellence demonstrated that they could use a technique known as nanoparticle-aided Raman spectroscopy to look at microscopic structures, including nascent tumors, deep inside the body. That team has now conducted extensive preclinical tests and shown that the gold nanoparticles can be safely administered into the colon and used with a Raman endoscope to image the inside of the large intestines.

New instrument keeps an electronic 'eye' on nanoparticles

Precision measurement in the world of nanoparticles has now become a possibility thanks to scientists at the University of California-Santa Barbara (UCSB). The UCSB research team has developed a new instrument capable of detecting and analyzing individual nanoparticles with diameters as small as a few tens of nanometers.

Improving health assessments with a single cell

Research led by scientists from the California Institute of Technology has shown that a new generation of microchips developed by the team can quickly and inexpensively assess immune function by examining biomarkers - proteins that can reflect the response of the immune system to disease - from single cells.

Fluorescent nanotubes illuminate the inner workings of laboratory mice

A team of investigators from Stanford University has developed an improved imaging method using fluorescent carbon nanotubes that create color images centimeters beneath the skin with far more clarity than conventional dyes provide. For a creature the size of a mouse, a few centimeters makes a great difference.

Nanopfeiler leuchten besser ohne Gold

Saeulen aus Galliumarsenid sind eine Alternative zu Schichten, denn sie wachsen auch auf Silizium in guter Qualitaet. Forscher des Paul-Drude-Instituts konnten jetzt den Nachweis erbringen, dass der haeufig verwendete Goldkatalysator die Eigenschaften der Saeulen empfindlich stoert.
