US government report highlights flaws in US nanotechnology effort

Posted by Jim Lewis on April 1st, 2014

The concern of the US GAO for a gap in nanomanufacturing is well-placed, but it is only half of the problem with the limited US vision of the impact of nanotechnology on the future world economy.

In mice, nanoparticle reduces inflammation in atherosclerotic plaques

Posted by Jim Lewis on March 5th, 2014

A reconstituted high-density lipoprotein nanoparticle reduces inflammation in advanced atherosclerotic plaques in mice. Will it work in humans to prevent repeat heart attacks and stroke?

Nanoparticles deliver cargo inside mitochondria

Posted by Jim Lewis on October 9th, 2012

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.

Shear-activated nanoparticles may target blood clots

Posted by Jim Lewis on August 16th, 2012

Studies in mice with otherwise fatal blood clots have shown that targeting a clot-busting drug to regions where blood flow is blocked restores circulation and increases survival with a much lower, safer dose of the drug.

Nanotechnology greatly improves sensitivity of common medical tests

Posted by Jim Lewis on June 21st, 2012

A new nanomaterial provides a three million-fold improvement in the sensitivity of common medical tests, potentially permitting earlier detection of cancer and Alzheimer’s disease.

Foresight Presents: “GENOGEN: Regenerating Skin for Life”, with Dr. Nancy Mize

Posted by Jim Lewis on May 20th, 2012

Nancy K Mize, PhD, Scientist, Innovator, and CEO of GENOGEN Inc., will continue Foresight’s local Bay Area community events with a lecture “GENOGEN: Regenerating Skin for Life”. GENOGEN is developing products that activate resident skin stem cells to stimulate local areas of regeneration of skin naturally – the way children heal.

Drug-resistant cancer cells cannot resist plasmonic nanobubbles

Posted by Jim Lewis on May 13th, 2012

Nanoparticles targeted to cancer cells by antibodies cannot achieve enough specificity to kill drug-resistant cancer cells while sparing normal cells, but can achieve enough specificity to produce nanobubbles only in cancer cells, so the drug only enters cancer cells.

Gold nanostars shuttled to cancer cell nucleus to release drug

Posted by Jim Lewis on April 24th, 2012

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.

Nanoparticles reduce tumors in clinical trial

Posted by Jim Lewis on April 17th, 2012

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.

Nanotechnology regrows blood vessels after ischemic damage

Posted by Jim Lewis on March 26th, 2012

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.

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 [...]
