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.
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.
Join us for an intellectually stimulating evening with best-selling author and tech analyst Sonia Arrison! Dinner and drinks will be served h’orderve/tapas-style at 7pm; Sonia will present at 8pm, with personalized, small-group Q&A on the future of technology to follow. Wednesday March 21, 2012 at Ristorante Don Giovanni, 235 Castro Street, Mountain View, CA 94041 [...]
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 [...]
A National Academy of Sciences panel has recommended a four-part research effort focused on preventing and managing any potential health and environmental risks of nanomaterials.
Human life after advanced nanotechnology has been developed will be fundamentally different from life up until that point.
Growing heart cells in a scaffold containing gold nanowires produces a tissue patch that is thicker and in which the cells beat synchronously as they do in healthy heart tissue.
DNA nanotechnology provides cell-surface sensors for real-time monitoring of single cells, including potential use in personalized medicine to test which drugs would be suitable for which individuals.
A nanotechnology therapy using targeted dendrimers shows promise against head and neck cancer in experiments in which human tumors are implanted into immunocompromised mice.
The world’s first synthetic organ transplant was a replica windpipe made from a nanocomposite scaffold seeded with the patient’s own adult stem cells.
Carbon nanofibers and a polymer were combined to create a composite to regenerate natural heart tissue.
A poll of NewScientist readers selected medical nanorobots as the technology that will have the biggest impact on human life in the next 30 years.
‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.
Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.
A cover article in Time magazine portrays the Singularity, Ray Kurzweil, AI, life extension, and nanotechnology as “an idea that rewards sober, careful evaluation.”
Catalytic nanomotors deliver nanoparticles containing drugs a thousand fold faster than do nanoparticles transported by Browninan motion.
Nanoparticles that deliver two anticancer agents simultaneously kill cancer cells more effectively than nanoparticles delivering the agents separately.
