Gold nanostars targeted to a protein over-expressed in most cancer cells are shuttled by that protein directly to the cancer cell nucleus where illumination with a laser light releases a drug that deforms the nucleus and kills the cell.
Clinical trials in patients with advanced or metastatic tumors using targeted nanoparticles to deliver a standard chemotherapeutic drug showed tumor shrinkage, even in the case of cancers for which that drug is not normally effective.
A set of rationally engineered transcriptional regulators for yeast will make it easier to build complex molecular machine systems in yeast, some of which may become useful additions to pathway technologies for atomically precise manufacturing and productive nanosystems.
A combination of a molecular motor protein and a nanopore protein has been harnessed for rapidly sequencing single DNA molecules.
In a rat model of ischemic damage, nanoparticle delivery of a growth factor and a coreceptor promotes regrowth of damaged blood vessels in seven days.
New protein repellent coating enhances the speed of carbon nanotube-based biosensors, pointing the way to faster, cheaper medical diagnostics.
Functioning DNA nanorobots to deliver specific molecular signals to cells were designed by combining DNA origami, DNA aptamers, and DNA logic gates.
A talk at TEDxBerkeley includes nanotechnology among the options for digital fabrication, one of five new rules of innovation.
New computational methods to explore the rapidly expanding collection of high resolution three-dimensional RNA structures reveal new RNA structural motifs, identifying additional building blocks for complex RNA nanostructures.
Artist’s conception of a nanopore drilled into a layer of graphene to speed up DNA sequencing. One of the greatest promises of near-term nanotechnoloogy is cheaper DNA sequencing to speed the development of personalized medicine. There are not only genetic differences between different patients, but also genetic differences between, for example, different cancers of the [...]
Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.
Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.
An article in The Guardian quotes Christine Peterson and Robert Freitas on the vision of molecular manufacturing. Freitas is quoted as expecting that the development of nanofactories could be done in 20 years for “on the order of” one billion dollars.
The first Master’s of Science in Nanomedicine degree program in US is announced. As an example of the rapidly developing potential of nanomedicine, a novel type of nanoparticle succeeded in two different mouse models in destroying a type of brain cancer that had previously been completely resistant to all treatment attempts.
A tutorial review available after free registration presents a theory-based exploration of the difficulty in moving from simple molecular switches to arrays of artificial molecular machines capable to doing substantial, useful external work.
RNA CAD tools developed for RNA-regulated control of gene expression in synthetic biology successfully engineered metabolic pathways in bacteria. Will engineering RNA-based genetic control systems lead to design tools for other RNA-based molecular machine systems?
Protein-like structures called peptoids can be formed into stable, free-floating nanosheets.
When can we expect advanced nanomachinery to be commercialized? Will any technologies not be affected in some way by advanced nanotechnology?
A tutorial review addresses the distinction between the many simple artificial molecular devices that are currently available and truly effective artificial molecular machines that would mimic the ubiquitous molecular machines present in living systems.
