Engineers at the University of Nebraska-Lincoln have shown how to create stacks of atomically thin crystal layers that are misaligned by 30 degrees from each other. That 30-degree rotation of each atomically thin layer relative to the one below it could lead to new electronic or optical properties, greater speed, and more functionality in less space.

Researchers at the University of Maryland School of Medicine have developed a new nanoparticle drug formulation that targets a specific receptor on cancer cells and appears to be more effective than a standard nanoparticle therapy currently on the market to treat metastatic breast cancer. The study found that the new nanoparticles bypass healthy cells and tissues and bind to tumor cells, dispersing evenly throughout the tumor while releasing the chemotherapy drug paclitaxel.
Scientists at Los Alamos National Laboratory have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes containing an integrated optical resonator, which allows them to function as lasers. These novel, dual-function devices clear the path towards versatile, manufacturing-friendly laser diodes. The technology can potentially revolutionize numerous fields, from photonics and optoelectronics to chemical sensing and medical diagnostics.

Researchers at the University of California Santa Barbara have been able to use a combination of gold nanorods and near-infrared light to destroy multidrug-resistant bacteria without antibiotics. These "phanorods" were applied to bacteria on in-vitro cultures of mammalian cells and then exposed to near-infrared light. The heat killed bacteria such as E. coli, P. aeruginosa, and V. cholerae.

Scientists at Brookhaven National Laboratory, Columbia University, and Van Andel Institute have developed a platform for assembling nanosized material components, or "nano-objects," of very different types—inorganic or organic—into desired 3-D structures. Synthetic DNA frames were engineered in the shape of a cube, octahedron, and tetrahedron. Inside the frames are DNA "arms" that only nano-objects with the complementary DNA sequence can bind to. These material voxels—the integration of the DNA frame and nano-object—are the building blocks from which macroscale 3-D structures can be made.
Scientists led by Rice University engineers have created light-powered nanoparticles to produce synthesis gas (syngas), a valuable chemical feedstock used in making fuels and fertilizer. The nanoparticles, tiny spheres of copper dotted with single atoms of ruthenium, are the key component in a low-energy, low-temperature photocatalytic process that could slash the carbon footprint for a major segment of the chemical industry.a
