Polymeric nanoparticles for tumor vaccines

The quest for an effective antitumor vaccine has received a boost from the results of work aimed at developing a nanoparticle that delivers tumor antigens to the immune system cells that trigger antibody production.

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.

Nanotechnology goes underground to boost oil production

The Bureau of Economic Geology at The University of Texas at Austin's Jackson School of Geosciences announces the Advanced Energy Consortium (AEC), a multimillion-dollar research consortium dedicated to the development of micro and nanotechnology applications to increase oil and gas production.

America's poor scientific literacy

Don't worry about that sound. It's just the ghost of C.P. Snow lamenting the persistent gulf between what he long ago labeled the two cultures - science and the rest of learning. The latest survey results have just come out on what laymen know about science, and the picture, mainly concerning Americans, is not pretty. But on the bright side, though most of us know relatively little about it, we generally like it.

University of Arkansas to receive $4 million nanotechnology grant

Gov. Mike Beebe announced today that nanotechnology researchers at the University of Arkansas will receive a $4 million grant from the state's General Improvement Fund. The money will benefit research and facilities in the College of Engineering and the J. William Fulbright College of Arts and Sciences.

Dark, dark nanotechnology

An ideal black object absorbs all of the colors of light and reflects none of them. Researchers at Rice University have demonstrated a new concept based on a low-density nanotube array material that can be engineered to dramatically change an object’s index of refraction and nanoscale roughness, hence, its optical reflection.
