Clean energy could lead to scarce materials

As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.

Nano-sized 'factories' churn out proteins

Drugs made of protein have shown promise in treating cancer, but they are difficult to deliver because the body usually breaks down proteins before they reach their destination. To get around that obstacle, a team of MIT researchers has developed a new type of nanoparticle that can synthesize proteins on demand. Once these "protein-factory" particles reach their targets, the researchers can turn on protein synthesis by shining ultraviolet light on them.

Successful human tests for first wirelessly controlled drug-delivery chip

Two years ago, researchers at the Massachusetts Institute of Technology (MIT) and the MIT-Harvard Center of Cancer Nanotechnology Excellence (CCNE) demonstrated in animal tests that an implantable microdevice could safely and accurately track a tumor marker in a living animal. Now these same investigators report on the first human clinical trials of an implantable microdevice capable of delivering drugs at the direction of an external wireless controller.

Nanoparticles enhance combination chemotherapy and radiation therapy

A mixture of current drugs and carbon nanoparticles shows potential to enhance treatment for head and neck cancers, especially when combined with radiation therapy, according to new research conducted by investigators at Rice University and the University of Texas MD Anderson Cancer Center. The therapy uses carbon nanoparticles to encapsulate chemotherapeutic drugs and sequester them until they are delivered to the cancer cells they are meant to kill.

DNA nanorobot targets therapeutic responses

Researchers at Harvard University have developed a robotic device made from DNA that potentially could seek out specific cell targets within a complex mixture of cell types and deliver important molecular instructions, such as telling cancer cells to self-destruct. Inspired by the mechanics of the body's own immune system, the technology might one day be used to program immune responses to treat various diseases.

Carbon nanotubes kill breast cancer stem cells

Researchers at Wake Forest Baptist Medical Center have shown that multi-walled carbon nanotubes injected into breast tumors and irradiated with a quick, 30-second laser beam, are effective at killing breast cancer stem cells.

Using radio waves to bake tumors

Nanothermal therapy - the use of nanoparticles to cook a tumor to death - is one of the many promising uses of nanotechnology to both improve the effectiveness of cancer therapy and reduce its side effects. Now, a team of investigators from the Texas Center for Cancer Nanomedicine has shown that liver cancer cells will take up targeted gold nanoparticles, absorb radio waves, and generate heat that damages the cells.
