Scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool, like a toaster that burns bread without getting hot.

Read moreDrugs 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.

Read moreTwo 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.

Read moreA 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.

Read moreResearchers 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.

Read moreNanothermal 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.

Read moreWith the aid of a novel set of lipid-coated, targeted quantum dots, researchers at Johns Hopkins University have developed a method for quantifying multiple specific biomarkers on the surfaces of individual cancer cells. This approach to quantitative biomarker detection stands to improve the histopathology methods used to diagnosis pancreatic and other cancers and enable the development of methods to spot cancer cells circulating in the blood stream.

Read moreNanotechnology offers powerful new possibilities for targeted cancer therapies, but the design challenges are many. Northwestern University scientists now are the first to develop a simple but specialized nanoparticle that can deliver a drug directly to a cancer cell's nucleus -- an important feature for effective treatment.
