Removing the necessity of providing several different chemical fuels in a series of distinct steps, a novel chemically-fueled molecular motor autonomously produces movement as long as the fuel supply lasts.
Recent research documents a structure-based rational design strategy combining molecular dynamics and single molecule imaging to improve the performance of a DNA tweezers that accurately positions an enzyme and its cofactor.
Combining computational nanotechnology with a noncontact-atomic force microscope probe tipped by a single CO molecule allowed researchers to visualize the dance of individual chemical bonds during a complex organic reaction on a silver surface.
The claim that the recently reported actuating nanotransducers (ANTS) produce forces "orders of magnitude larger than any produced previously" is challenged by a nanocrystal carbon nanotube device reported 11 years ago.
Atomic resolution measurement of quasi-particle tunneling maps of spin-resolved states reveals interference processes that allow simulation of processes important for developing quantum computers based on atomically precise doping of silicon.
Computational design of an enzyme that carboligates three one-carbon molecules to form one three-carbon molecule, an activity that does not exist in nature, provides proof-of-principle for a novel metabolic pathway for carbon fixation.
A nanoengine 100 times more powerful than known nanomotors and muscles was demonstrated using the aggregation and dispersal of gold nanoparticles coated with a polymer that undergoes a rapid transition from hydrophobic to hydrophilic.
Christine Peterson will speak on "High-Leverage Altruism" at the fourth annual conference of Effective Altruism, using reason and evidence to improve the world as much as possible, and on nanotechnology at the Singularity University Global Summit, the definitive gathering for those who understand the critical importance of exponential technologies.
A DNA strand capable of forming a triple helix with a portion of the DNA double helices in a macroscopic DNA crystal enhances the weak interactions holding the crystal together so that the crystal remains stable in the absence of a high ionic strength environment.
A specially designed triplex forming oligonucleotide bearing a cargo molecule binds to a specific sequence in the major groove of a DNA double helix to form a modified DNA tile that self assembles into a macroscopic crystal in which each helix carries a cargo molecule positioned to sub-nanometer precision.
Small, stiff, rectangular rods made using scaffolded DNA origami bypass drug resistance mechanisms in the membranes of a cultured leukemia cell line and release enough therapeutic drug to kill the cancer cell.
Foresight Institute, a leading think-tank for transformative future technologies, such as nanotechnology, synthetic biology, and artificial intelligence, announced that Julia Bossmann has joined the organization as president.
Increasing efficiency and utilization and lowering costs for harvesting, converting, transporting, and storing energy produced from sunlight provides a showcase for a variety of nanoscale materials, structures, and processes.
California Institute of Technology is holding a symposium to honor Paul Rothemund's seminal contribution to the field of DNA nanotechnology: the research paths opened by the technology, and where they might lead.
Thousands of amateurs playing the online RNA folding game Eterna, backed up by a real-world automated lab testing their predictions, have provided insights to improve the algorithms computers use to design RNA molecules.
Do sophisticated medical applications of 3D printing, like printing titanium bones or human tissues, that portend wider use, also perhaps point toward eventual nanoscale applications as the technology improves?
