DNA nanotechnology uses DNA molecules as programmable "Legos" to assemble nanostructures. But the structure of DNA is very simple and lacks the diversity of proteins, while the assembly of proteins is difficult to control with the precision of DNA. How about combining both DNA and proteins? Scientists have built a cage made of protein and DNA building blocks by using covalent bonds between them.

By using an aberration-corrected scanning transmission electron microscope, scientists were able to monitor real-time atom rearrangement during the synthesis of intermetallic nanoparticles made of platinum-tin alloy. These nanoparticles have applications in energy-efficient fuel conversion and biofuel production.

Leukemia cells have an impaired ability to get rid of iron. A nanoparticle drug called ferumoxytol delivers additional iron to these cells. The excess iron causes the leukemia cells to die. Ferumoxytol is already approved to treat anemia, so researchers know the drug is safe.

Researchers have developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive lenses to realize portable imaging systems and optoelectronic devices. The flat and versatile lens has a thickness 100 times smaller than the width of a human hair.
