Nanotechnology researchers in London have used a scanning tunneling microscope to create atomically precise quantum states from dangling bonds on a silicon surface.

Revolution of DNA around a central channel, rather than rotation, is the method used by a viral molecular motor to package DNA. A structure facilitating bottom-up assembly may lead to roles in nanotechnology for these nanomotors.

In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information [...]

By forcing the geometry of the junctions upon which DNA nanotechnology depends, researchers have increased the collection of 2D and 3D structures that they can build to include wire frames and mesh structures.

Researchers from UCLA’s California NanoSystems Institute and Northwestern University have combined multiple imaging techniques to produce high quality 3D images of platinum nanoparticles, allowing advanced visualization of atomic-scale structural defects (an important advancement over X-ray crystallography). The original 2012 work, published in Nature and posted by Jim Lewis here, used electron tomography to study 10-nm [...]

Nanoparticles decorated to avoid immune system recognition were tested in mice and shown to survive longer and deliver more imaging dye and drug to tumor cells.

A proposed large project to produce a dynamic map of the functional connectome of the human brain will require a convergence of neuroscience, biotechnology, nanotechnology, and computation, and may therefore spur the development of advanced nanotechnology leading to molecular manufacturing.

Core-shell nanocapsules deliver a potent protein complex to the nucleus of cancer cells where it induces them to commit suicide, while the complex degrades harmlessly in the cytoplasm of normal cells.

In a 47-minute interview Christine Peterson discusses the future that science and technology is bringing over the next few decades, and how to get involved to push the future in a positive direction.

An interview with Foresight Co-Founder and Past President Christine Peterson covering both the current state and the future prospects of nanotechnology is available on Youtube.

Scanning probe manipulation of individual atoms and small molecules were amongst the early laboratory successes that helped bring broad scale attention to the feasibility and potential of nanoscale technologies, especially molecular fabrication. Basic manipulations of atoms and bonds by scanning probe have become familiar capabilities that follow similar protocols: the STM tip is precisely positioned [...]

A demonstration that most fundamental biological processes can be implemented in a test tube as efficiently as in live bacteria provides synthetic biology the tools to create a ‘new industrial revolution’, which may or may not lead to more general molecular manufacturing.

A small molecular machine based on a rotaxane molecule autonomously added three amino acids in a programmed order to a seed tripeptide to form a hexapeptide

Electrons from a scanning tunneling microscope tip turn a five-arm rotor connected via a single ruthenium atom bearing to a tripod anchoring the molecular motor to a gold surface.

A theoretical proposal for optical tweezers and an experimental optical focusing device both depend upon electromagnetic waves trapped and guided along metal-insulator interfaces. Will these advances provide tools for manipulating molecular building blocks?

In two different sets of experiments a German research group has shown that scaffolded DNA origami can be used to assemble complex structures with precise sub-nanometer positional control, and that constant temperature reaction can greatly increase yields and decrease production times.

One research group working with rotaxanes and another group working with carbon nanotubes have provided two very different solutions to the problem of producing motion via artificial muscles at different scales from the nano to the macro.

A study of a biological molecular machine has shown that the machine functions most effectively when it uses chemical bonds just barely strong enough to survive the power stroke of the machine.

A set of 32-nucleotide single strand DNA bricks was designed so that each can interact independently with four other DNA bricks so that sets of hundreds of bricks can self-assemble into arbitrarily complex 25-nm 3D shapes, each comprising 1000 8-base pair volume elements.

Five proteins were designed from scratch and found to fold into stable proteins as designed, proving the ability to provide ideal, robust building blocks for artificial protein structures.
