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.
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.
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.
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.
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.
The potential of carbon nanotubes to diagnose and treat brain tumors is being explored through a partnership between NASA's Jet Propulsion Laboratory, Pasadena, Calif., and City of Hope, a leading cancer research and treatment center in Duarte, Calif.
Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg’s uncertainty principle usually would prohibit, according to a study published Jan. 17 in the journal Nature.
A diverse group of nanotechnology stakeholders, including non-governmental organizations, large and small companies and research organizations, applaud the inclusion in the Consolidated Appropriations Act for Fiscal Year 2008 of a measure that will aid in the development and implementation of a comprehensive federal nanotechnology environmental, health, and safety (EHS) research strategy.
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.
The California Institute of Nanotechnology is offering Certified Professional Development Training in Nanotechnology and Clean Technology. The training programs will be held in conjunction with the Emerging Tech Investment Forum, this January 23-25, 2008 at their Corporate Offices in San Jose.
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.
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.
A seminar on January 16, 2008 from 7:00 - 9:00 pm at the London School of Economics addresses the rapidly changing world economic landscape: 'The Power Shift to the East: The American Century Is Ending'.
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.
