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.
A nanotechnology-based sensor provides fast, inexpensive, ultrasensitive assay of microRNA pattern to detect cancer using DNA immobilized on a synthetic gold nanoprism.
Nanometer-level control of the beam path of a scanning transmission electron microscope nudges an amorphous material into atomically precise epitaxial growth.
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.
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.
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.
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 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.
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.
By precise control of several factors, uniform high-performance monolayers of the semiconductor MoS2 have been obtained and used to fabricate field-effect transistors.
