io9 talks to Kathleen Ann Goonan about nanopunk and jazz

Science fiction author Kathleen Ann Goonan was writing about nanotechnology before most people even know it existed. Her Nanotech Quartet, including her celebrated first novel Queen City Jazz, is about a future United States where nanotech has gone wild and turned cities into living entities - and reprogrammed people to reenact scenarios from US history and literature.

Iridescence workshop promotes nature's nanotechnology

The phrase 'sex sells' takes on special significance when scientists and students gather. While nature's showiest subjects step out to promote reproductive success and survival with bright colors, flash and iridescence in feathers, scales, petals and wings, biologists, physicists, behaviorists and materials scientists will delve into what’s behind all the bling at a workshop on 'Iridescence' to be held Feb. 6-9 at Arizona State University in Tempe, Ariz.

Nanotechnology development initiative proposed in Wisconsin

The NanoSTEM initiative recognizes that the Chippewa Valley is positioned to be a hub of nanotechnology activity. It would provide additional resources to the Universities of Wisconsin-Eau Claire and Stout and to Chippewa Valley Technical College, and provide tax incentives for businesses that partner with the schools to develop nanotechnologies.

New technique could dramatically lower costs of DNA sequencing

Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably.

Nanorod-aptamer combo targets tumors

Aptamers, short stretches of DNA or RNA that can act much like antibodies, have shown promise as targeting agents for selective nanoparticle trafficking to tumors. Their ability to recognize and bind to tumor-specific molecules is undisputed, but the strength with which aptamers bind to their molecular targets is often insufficient to act as an effective targeting agent under clinically relevant conditions.

Tumor-associated enzyme triggers drug release from nanoparticles

Cancer cells display a variety of proteins on their outer membranes that are not present on the surface of normal cells. Although these proteins are likely to be critical to the survival or metastatic spread of cancer, investigators at North Dakota State University have turned one of these proteins against the malignant cell, using it to trigger the release of dye molecules entrapped in a nanoparticle.

Nanoparticles harvest tumor biomarkers

The long and challenging effort to find blood-borne markers for cancer and other diseases may soon enter a new realm of success using a new nanoparticle that preferentially and rapidly removes small proteins and other molecules from blood while simultaneously protecting them from degradation.

Gold nanoparticles shine brightly in tumors

Solid gold nanoparticles have long been used to treat rheumatoid arthritis and more recently have shown promise in treating various types of cancer. Now, thanks to work by Shuming Nie, Ph.D., and his colleagues at the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology, these same nanoparticles could serve as a powerful tumor-homing beacon for detecting microscopic tumors or even individual malignant cells.
