Making fuel cells practical and affordable will not happen overnight. It may, however, not take much longer. With advances in nanostructured devices, lower operating temperatures, and the use of an abundant fuel source and cheaper materials, a group of researchers led by Shriram Ramanathan at the Harvard School of Engineering and Applied Sciences (SEAS) are increasingly optimistic about the commercial viability of the technology.

Researchers are creating a system that harvests heat from an engine's exhaust to generate electricity, reducing a car's fuel consumption. The effort is funded with a $1.4 million, three-year grant from the National Science Foundation and the U.S. Department of Energy.

To improve the tumor-specific delivery of drug to tumors, a team of investigators has created a system of nanoparticles-within-a-nanoparticle that can be directed to and concentrated at the site of tumor using a magnetic field. Once at the tumor site, radiofrequency irradiation triggers drug release from the nanoparticles, bathing the tumors in drug and markedly reducing the growth of the tumors.

In attempt to develop a new therapeutic approach to treating peritoneal metastases, a research team at Boston University has developed a novel, drug-loaded polymeric nanoparticle that responds to the acidic pH inside tumor cells by expanding, releasing the anticancer agent paclitaxel slowly over a period of 24 hours.

Gold nanoparticles have shown promise as miniature thermal scalpels that when irradiated with near-infrared light are capable of cooking tumors to death. Now, a team of investigators have found that gold nanoshells can be used to deliver just a little heat to breast tumor cells already treated with radiation, boosting the killing power of both therapies.

In 2007, Mehmet Toner and Daniel Haber and their collaborators at Massachusetts General Hospital and Harvard Medical School developed a microfluidic device capable of trapping rare circulating tumor cells (CTCs) from the blood of cancer patients. Since then, these investigators, working with Harvard Medical School colleague Shyamala Maheswaren, have shown that captured CTCs can be used to characterize tumors from patients with lung and prostate cancer.
