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.
Precise matching of STM images and theoretical calculations provides exact lattice locations of dopant atoms, advancing the prospects for silicon-based quantum computers.
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.
Chains of monomers joined by non-biological peptoid bonds follow different rules of self-assembly and form structures not found in chains joined by the peptide bonds used to form proteins.
An engineered protein controls the assembly of C60 fullerene molecules into an atomically precise lattice that conducts electricity while neither component alone would.
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 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.
Structural DNA nanotechnology: progress toward a precise self-assembling three dimensional scaffold by building macroscopic crystals from nanoscale structures.
Five calcium ions held several micrometers apart in an ion trap and manipulated by laser pulses implement Shor’s factorization algorithm more efficiently than previous implementations.
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.
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.
A rotor with DNA origami parts held together by an engineered tight fit instead of by covalent bonds can revolve freely, driven by Brownian motion and dwelling at engineered docking sites.
Two research teams present two different methods for using single strands of DNA to link various nanoparticles into complex 3D arrays: one using DNA hairpins for dynamic reconfiguration and the other using a DNA origami scaffold.
