RNA CAD tool for synthetic biology may facilitate RNA nanotechnology

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?

Mechanical pressure produces atomically-precise, multifunctional 2D sheets

Protein-like structures called peptoids can be formed into stable, free-floating nanosheets.

Christine Peterson on current state and future potential of nanotechnology

When can we expect advanced nanomachinery to be commercialized? Will any technologies not be affected in some way by advanced nanotechnology?

A molecular switch with a single proton switched by a single electron

How small could a molecular switch be made? It is difficult to think of one smaller than the single proton switch just demonstrated by this group in Germany.

Know a young visionary who deserves a large grant? Deadline Dec 31

The Thiel Foundation is offering $100,000 grants to innovators age 19 or younger who want to skip college and focus on their work, their research, and their self-education—Deadline Dec 31.

Turning nanoparticles into multicomponent three-dimensional nanostructures

Controlling the chemical processes of corrosion and plating at the nanoscale has been used to fabricate from inorganic nanoparticles complex three-dimensional objects with hollow interiors.

Tutorial review of the promise of artificial molecular machines

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.

Lecture by Eric Drexler at Oxford on physical law and the future of nanotechnology (video)

In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.

New light-sensitive polymer to control drug release from nanoparticles

A new polymer that disintegrates in response to harmless radiation that can penetrate several inches into human tissue may lead to nanoparticles that release their drug cargo only at a desired time and place.

Darpa seeks nanotechnology defense against novel pathogens

To counter the threat of evolved or engineered resistance of pathogenic bacteria to antibiotics, Darpa proposes to use nanotechnology to develop “Rapidly Adaptable Nanotherapeutics”.
