Nanotechnology, DNA sequencing, and personalized medicine

Posted by Jim Lewis on February 20th, 2012

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 [...]

Foresight co-founder among panelists discussing role of technology in human existence

Posted by Jim Lewis on January 23rd, 2012

Human life after advanced nanotechnology has been developed will be fundamentally different from life up until that point.

First Master's of Science in Nanomedicine degree program in US announced

Posted by Jim Lewis on January 6th, 2012

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.

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”.

DNA nanosensors profile gene activity to reveal state of cells

Posted by Jim Lewis on November 18th, 2011

Small DNA molecules fluoresce in the presence of specific transcription factors, sensing which genes are being expressed in that cell, potentially allowing cancer treatments to be personalized, and the quality of stem cells to be monitored.

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.

Viruses guide nano-assembly of biomaterials

Posted by Jim Lewis on October 27th, 2011

This contribution has been forwarded by Ivo Rivetta. Researchers at UC Berkeley have taken a bioinspired approach to control the nanostructure of deposited thin films. In living organisms, the orientation of collagen in tissue determines its properties: For instance, a number of blue-skinned animals, including the mandrill monkey, derive their coloring not from pigment, but [...]

Destroying cancer cells by incorporating an artificial biological computer

Posted by Jim Lewis on October 14th, 2011

A complex piece of DNA that acts as a biological computer when it is inserted into cells determines whether or not the cell is a specific type of cancer cell, and if so, initiates the suicide of that cell.

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: [...]

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.

A four-artificial-neuron network from 112 DNA strands

Posted by Jim Lewis on July 22nd, 2011

A neural network made from 112 DNA strands organized into four artificial neurons was trained with four pieces of information to answer questions.

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.

Nanotechnology therapy for head and neck cancer shows promise

Posted by Jim Lewis on July 15th, 2011

A nanotechnology therapy using targeted dendrimers shows promise against head and neck cancer in experiments in which human tumors are implanted into immunocompromised mice.

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.

Nanotechnology protects mice infected with lethal dose of flu virus

Posted by Jim Lewis on June 20th, 2011

Treatment of mice previously infected with a lethal dose of flu virus with a nanotechnology-based drug lowered viral load a thousand fold.
