Independent rotation of two wheels attached to either end of an axle has been achieved in a light-driven artificial molecular motor, suggesting a basis for a nanometer-scale transport system.
DNA nanotechnology produces an artificial molecular machine that changes shape when it encounters a specific antibody or other protein molecule, and emits light to signal the target’s presence.
A novel application of supramolecular chemistry allows molecules to join in only one direction, providing a new way to control the shape of large molecules.
A lipid bilayer supported by a mica surface assisted the mobile self-assembly of DNA nanostructures of various shapes into micrometer-scale 2D lattices.
Prof. Art Olson discussed how we understand what we cannot see directly, how we integrate data from different sources, and how to develop software tools to move forward.
Hijacking a viral method of replicating circular genomes, ball-of-yarn-like DNA clews are used to transport the protein and guide RNA molecules needed for gene editing into the cell nucleus.
DNA strands decorating cell membranes like ‘Velcro’ program the adhesion of cells to other cells or to extracellular matrices to build tiny tissue models.
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.
The ability to dope graphene nanoribbons with boron atoms to atomic precision opens a range of possible new applications, from chemical sensing to nanoelectronics to photocatalysis to battery electrodes.
Designing a small DNA origami that can fold in several almost equivalent ways demonstrates how understanding and guiding the folding pathway can improve the efficiency of the folding process, potentially leading in more complex situations to higher yields of the desired nanostructure and fewer misfolded structures.
Simple molecular switches based upon bistable mechanically interlocked molecules can be incorporated within pre-assembled metal organic frameworks and addressed electrochemically.
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.
A pliers-shaped molecule in which two covalently linked naphthalene moieties serve as the hinge connecting the two halves of the pliers, and each naphthalene connects the hydrophobic handle with the hydrophilic jaw of that half, opens and closes in response to surprisingly little energy applied to a molecular monolayer.
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 new set of design rules enables constructing any wireframe nanostructure, which may lead to new medical applications and new nanomachines.
Modeling DNA strand displacement cascades according to three simple rules can in principle mimic the temporal dynamics of any other chemical system, presenting a method to model regulatory networks even more complicated than those of biology.
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.
Functional ribosomes with subunits engineered to not separate at the completion of each protein translation cycle make possible engineering systems to make a variety of novel polymers with novel properties.
