Novel nanoconjugate delivers synergistic combination of microRNAs to treat cancer

Two microRNAs with synergistic effects, one that suppresses tumor growth and another than inhibits tumor promotion, are combined in an RNA triple helix, complexed with a dendrimer to form nanoparticles, which are incorporated with a polymer to form a hydrogel that inhibits tumor growth when applied to the tumor.

Ultrasensitive microRNA assay with nanosensor to detect cancer

A nanotechnology-based sensor provides fast, inexpensive, ultrasensitive assay of microRNA pattern to detect cancer using DNA immobilized on a synthetic gold nanoprism.

Atomic precision in sculpting 3-D objects

Nanometer-level control of the beam path of a scanning transmission electron microscope nudges an amorphous material into atomically precise epitaxial growth.

Generating hydrogen with single atom catalysts

Single cobalt atoms have been positioned in nitrogen-doped graphene to catalytically produce hydrogen from water almost as effectively as using vastly more expensive platinum catalysts.

Catalytic micromotors demonstrate carbon dioxide removal from water

A micromotor covered with the enzyme carbonic anhydrase zips through water rapidly converting dissolved carbon dioxide to the bicarbonate ion, which can then be precipitated as calcium carbonate.

Nanotechnology provides sensors for liver-on-chip drug testing

Adding nanotechnology-based optoelectronic sensors to human cells cultured on a chip keeps the cells healthy long enough to replace animal testing with a human liver-on-a-chip.

Femtosecond imaging with near nanometer spatial resolution

Analysis of multiple diffraction images provides high contrast, high quality, full field 3D imaging of surfaces illuminated by extreme ultraviolet photons from a tabletop laser.

A tunable bandgap by doping a few atomic layers of black phosphorous

A vertical electrical field from dopant atoms of potassium added to the surface of a few stacked layers of phosphorene tunes the band gap of black phosphorous, possibly leading to novel electronic and optoelectronic devices.

Another nanotechnology computer memory breakthrough from Feynman Prize winner

A novel nanostructured material based on tantalum oxide could make possible non-volatile crossbar array memories that store up to 162 gigabits in 3-D memory stacks.
