DNA nanomachine lights up to diagnose diseases

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.

Chirality-assisted synthesis a new tool for nanotechnology

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.

Surface assisted self-assembly of DNA origami nanostructures

A lipid bilayer supported by a mica surface assisted the mobile self-assembly of DNA nanostructures of various shapes into micrometer-scale 2D lattices.

Free online edition of The Feynman Lectures on Physics

A free to read online edition of the classic 3-volume physics text developed from Richard Feynman’s legendary Cal Tech physics lectures, specially designed for online reading, has been made available by the California Institute of Technology and the Feynman Lectures Website.

Conference video: New Methods of Exploring, Analyzing, and Predicting Molecular Interactions

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.

Foresight co-founder on the future of the human lifespan

Optimized Geek podcast featured Christine Peterson on the future of nanotechnology, human lifespan, artificial intelligence, finding love, and other topics.

Nanotechnology carries gene editing package into cells

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 nanotechnology guides assembling cells into ‘Organoids’

DNA strands decorating cell membranes like ‘Velcro’ program the adhesion of cells to other cells or to extracellular matrices to build tiny tissue models.

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.

Atomically precise boron doping of graphene nanoribbons

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.
