Christine Peterson on current state and future potential of nanotechnology

Posted by Jim Lewis on December 21st, 2011

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

Turning nanoparticles into multicomponent three-dimensional nanostructures

Posted by Jim Lewis on December 12th, 2011

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.

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

Posted by Jim Lewis on December 6th, 2011

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

Posted by Jim Lewis on December 4th, 2011

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

Posted by Jim Lewis on November 30th, 2011

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

Will new piezoelectric materials lead to new tools for nanotechnology?

Posted by Jim Lewis on November 27th, 2011

Will the integration of a single-crystal material with “giant” piezoelectric properties onto silicon make possible scanning probe microscopes on a chip?

Leveraging nanoforces to increase biosensor sensitivity

Posted by Jim Lewis on November 16th, 2011

This contribution has been forwarded by Ivo Rivetta. The primary forces on the nanometer scale are scaled versions of what we experience on a day to day basis. Instead of gravity, surface forces such as water tension and electric charge dominate. As an example, compare wet basketballs and wet sand. The weight of the basketballs [...]

Carbon nanotube muscles could propel future medical nanorobots (video)

Posted by Jim Lewis on October 31st, 2011

Yarn woven from carbon nanotubes provides a thousand times more rotation than is obtained from other artificial muscles, and could be made into motors to provide propulsion for micrometer-sized medical nanorobots.

Using DNA as bonds to build new materials from nanoparticles

Posted by Jim Lewis on October 31st, 2011

Varying the length of the DNA used to connect the nanoparticles provides for a wide variety of nanoparticle sizes and crystal symmetries.

Magnetic nanoparticles to cook brain cancer go into trial in patient

Posted by Jim Lewis on October 12th, 2011

Nanotechnology has been applied to produce various types of nanoparticles that can deliver toxic agents specifically to the cancer cells. Many of these approaches have shown promise in animal studies. One approach using magnetic nanoparticles has now gone into trials in patients. From “Nano-therapy that cooks deadly brain tumors advances in Germany,” by Ryan McBride: [...]

Boston College Researches Uncover Early Phases of Carbon Nanotube Growth

Posted by Jim Lewis on October 7th, 2011

Christopher William Ince Jr. writes about a new insight into how nanotubes grow, which may lead to even more useful technological applications for these nanostructures: Physicists Zhifeng Ren and Hengzhi Wang of Boston College have discovered two initial stages of carbon nanotube growth previously obscured during the growth process. What the researches found is that [...]

Nanotechnology for Heart Repair Advances

Posted by Jim Lewis on September 29th, 2011

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.

Long nanowires with controlled orientation grown on sapphire

Posted by Jim Lewis on August 31st, 2011

Growing semiconductor nanowires along crystallographic planes of sapphire provides well-structured nanowires with excellent optical and electronic properties.

Green Nanotechnology Roadmap Highlights Opportunities and Challenges

Posted by Jim Lewis on August 23rd, 2011

A green nanotechnology roadmap released by the American Chemical Society describes the opportunities and barriers to developing commercial applications of nanomaterials that present little threat of harm to health and the environment, and concludes with an action agenda to more forward.

DNA nanotechnology provides detailed monitoring of single cells

Posted by Jim Lewis on July 19th, 2011

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.

First synthetic organ transplant made possible by nanotechnology

Posted by Jim Lewis on July 11th, 2011

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.
