Inexpensive separation method of graphene developed

The problem with commercializing graphene that is synthesized onto metals over a wide area is that it can not be separated from the metal. However, a groundbreaking separation technology which is both cheap and environment friendly has been developed.

The weird nanoscale phenomenon of remote heating

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.

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.
