Extreme darkness: Carbon nanotube forest covers ultra-dark detector

Harnessing darkness for practical use, researchers at the National Institute of Standards and Technology (NIST) have developed a laser power detector coated with the world's darkest material - a forest of carbon nanotubes that reflects almost no light across the visible and part of the infrared spectrum.

Ultrasensitive nanotube biosensor can detect proteins, aid in illness diagnosis

A cluster of carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins. With further development, this biosensor could provide a crucial new diagnostic tool for the detection of cancer and other illnesses.

Porous silica nanoparticles deliver anticancer therapy

In cancer research, nanotechnology holds great promise for the development of targeted, localized delivery of anticancer drugs, in which only cancer cells are affected. By carrying out comprehensive studies on mice with human tumors, scientists at the University of California, Los Angeles, have obtained results that move the research one step closer to this goal.
