'Nano-Velcro' technology improves capture of circulating cancer cells

Circulating tumor cells, which play a crucial role in cancer metastasis, have been known to science for more than 100 years, and researchers have long endeavored to track and capture them. Now, a UCLA research team has developed an innovative device based on Velcro-like nanoscale technology to efficiently identify and "grab" these circulating tumor cells, or CTCs, in the blood.

Ultra fast photodetectors out of carbon nanotubes

Carbon nanotubes have a multitude of unusual properties which make them promising candidates for optoelectronic components. However, so far it has proven extremely difficult to analyze or influence their optic and electronic properties. A team of researchers has now succeeded in developing a measurement method allowing a time-based resolution of the so-called photocurrent in photodetectors with picosecond precision.

Book makes nanotechnology accessible to smaller readers

Although Dr. Moon Kim's zeal for nanotechnology springs in part from years of research into the structural characterization of advanced electronic materials, he doesn't see why kids shouldn't be exhilarated by the very small as well. Now he's taken two steps to help make that happen, writing a nanotechnology primer for kids and starting an internship program that brings them into his lab for weeks at a time.

New microscope produces dazzling 3D movies of live cells

A new microscope invented by scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail. The microscopy technique images at high speed, so researchers can create dazzling movies that make biological processes, such as cell division, come alive.
