Targeted dendrimer advances in preclinical studies

Although a variety of nanoparticles continue to show promise for improving cancer imaging and therapy, regulators and drug developers are concerned that these delivery systems may prove difficult to manufacture on a consistent basis, which is key for any agent designed for use in humans. A new study provides data showing that such concerns can be overcome.

Nanotechnology advances brain cancer detection and therapy

Brain cancer is one of the most aggressive and lethal of malignancies, made even more difficult to treat by the fact that most anticancer drugs have a hard time even getting to the tumors. Now, studies by three different groups of researchers show that targeted nanoparticles hold promise for solving this delivery problem.

Researchers probe biological fate of carbon nanotubes with Raman spectroscopy

Carbon nanotubes have shown real promise as highly accurate vehicles for delivering antitumor agents into malignant cells, but a dearth of data about what happens to the tubes after they discharge their medical payloads has been a major stumbling block to progress. Now, two studies at the Center for Cancer Nanotechnology Excellence Focused on Therapy Response have revealed some reassuring answers after months of tracking the tiny tubes inside mice.

U.S. leads world in PHEV battery R&D, lags in capabilities to make them

During opening testimony before the House Appropriations Subcommittee on Energy and Water Development, Argonne's Don Hillebrand noted that while the United States is the dominant player in the development of battery materials and chemistries for hybrid vehicles and Plug-in Hybrid Electric Vehicles (PHEV) with the help of progressive research conducted at U.S. Department of Energy national laboratories, including Argonne, the nation lags behind the world in adopting capabilities to make such batteries.
