By tethering hundreds of tiny particles to the surfaces of tumor cells in the presence of a mechanical force, an MIT team made the cells much more vulnerable to attack by a drug that triggers cancer cells to commit suicide.

Tethered nanoparticles make tumor cells more vulnerable

New strategy could improve performance of some immune-based drugs.

MIT aerospace researchers have demonstrated that some randomness in the arrangement of carbon atoms makes materials that are lighter and stronger, shown at lower right in illustration, compared to a more densely packed and tightly ordered structure, shown lower left. They formed a type of disordered graphite-like carbon material that is often called glassy carbon by “baking” a phenol-formadehy...

Disorder can be good

Researchers discover that chaos makes carbon materials lighter and stronger.

Researchers have developed a type of steel with three characteristics that help it resist microcracks that lead to fatigue failure: a layered nanostructure, a mixture of microstructural phases with different degrees of hardness, and a metastable composition. They compared samples of metal with just one or two of these key attributes (top left, top right, and bottom left) and with all three (bottom...

Researchers at MIT have discovered new way of using laser light to tune electronic energy levels in two-dimensional films of crystal. The discovery could ultimately pave the way for the development of so-called “valleytronic” devices, which harness the way electrons gather around two equal energy states, known as valleys.

Toward “valleytronic” devices for data storage or computer logic systems

Researchers have discovered a new way to tune electronic energy levels in some 2-D materials.

New research shows that electrons passing through a narrow constriction in a piece of metal can move much faster than expected, and that they move faster if there are more of them — a seemingly paradoxical result. In this illustration, the orange surface represents the potential energy needed to get an electron moving, and the “valley” at center represents the constricted portion.

Electrons go superballistic

Newly discovered phenomenon accelerates electrons as they enter a viscous state.

Mild heating of graphene oxide sheets makes it possible to bond particular compounds to the sheets’ surface, a new study shows. These compounds in turn select and bond with specific molecules of interest, including DNA and proteins, or even whole cells. In this image the treated graphene oxide on the right is nearly twice as efficient at capturing cells as the untreated material on the left.

Graphene sheets capture cells efficiently

New method could enable pinpoint diagnostics on individual blood cells.

This high-resolution transmission electron micrograph of particles made by the research team shows the particles’ highly uniform size and shape. These are iron oxide particles just 3 nanometers across, coated with a zwitterion layer. Their small size means they can easily be cleared through the kidneys after injection.
