RNA-protein motor for unidirectional movement of DNA in nanomachinery

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.

Nanotechnology revolution: An interview with Eric Drexler

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… Continue reading Nanotechnology revolution: An interview with Eric Drexler

Computationally designed peptide sneaks nanoparticles past immune system

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 teenager's step toward nanomedicine innovation

In this Forbes interview, contributor John Nosta introduces us to a teen worth watching: fifteen-year-old Jack Andraka, whose effort to design a nanotube-based sensor for pancreatic cancer detection was initially ignored. The interview taps into some aspects of how innovation occurs and the challenges of bringing new ideas to fruition – aspects which transcend age,… Continue reading A teenager's step toward nanomedicine innovation

Nanotechnology delivers potent anti-cancer agent where it needs to go

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.

Christine Peterson on pushing the future in a positive direction

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.

Christine Peterson interviewed on nanotechnology

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.

Synthetic biology industrial revolution inspires hope for molecular manufacturing

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.

Shape may play an important role in nanoparticle-based therapeutics

Researchers from Johns Hopkins and Northwestern Universities developed a set of shape-tunable DNA-copolymer nanoparticles that incorporate a fixed amount of DNA yet display as much as 1,680-fold difference in transfection efficiency in rat liver studies. The study may shed new light on the importance of shape in nanoparticle-based drug delivery and gene therapy.

Nanoparticles deliver cargo inside mitochondria

Optimizing the size and charge of nanoparticles engineered from polymers delivers drugs directly to mitochondria, effectively treating cells with drugs for a variety of diseases.
