Protein, RNA, DNA: Nanotechnology finds a multitude of paths to attack cancer cells

Posted by Jim Lewis on May 2nd, 2011

Protein, RNA, DNA provide very different molecular architectures for nanotechnology to adopt to deliver drugs to cancer cells while sparing healthy cells.

'Good Cholesterol' nanoparticles silence cancer-promoting genes and destroy cancer cells

Posted by Jim Lewis on April 27th, 2011

‘Good Cholesterol’ nanoparticles are non-toxic and use the need of cancer cells for HDL cholesterol to deliver RNA molecules to silence the expression of cancer-promoting genes.

Nanotechnology boosts anticancer drug cocktail many times over

Posted by Jim Lewis on April 22nd, 2011

Porous silica nanoparticles covered with a lipid bilayer deliver large doses of drugs and kill cancer cells a million fold better than do simple liposomes.

Nanotechnology promises low-cost method to squash superbugs

Posted by Jim Lewis on April 14th, 2011

Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.

Physicist and television host sees future for nanotechnology and AI

Posted by Jim Lewis on March 24th, 2011

In a review of physicist and television host Michio Kaku’s latest book, Foresight advisor Glenn Reynolds finds reason for optimism, but also cause for concern in the career choices of today’s brightest minds.

Time magazine cover article on the Singularity, Ray Kurzweil, AI and nanotechnology

Posted by Jim Lewis on February 17th, 2011

A cover article in Time magazine portrays the Singularity, Ray Kurzweil, AI, life extension, and nanotechnology as “an idea that rewards sober, careful evaluation.”

Molecular machine switches magnetic state at room temperature

Posted by Jim Lewis on January 29th, 2011

Irradiation with two wavelengths of visible light switches the position of a nitrogen atom close to a nickel ion, and in the process switches the magnetic state of the nickel ion.

Sixteen-year-old nanotechnologist wins Intel Fair and attends State of the Union speech

Posted by Jim Lewis on January 26th, 2011

Sixteen-year-old nanotechnologist Amy Chyao won top prize at the 2010 Intel International Science and Engineering Fair for her work on a nanoparticle to attack cancer cells and joined three other winners in Michelle Obama’s box during the State of the Union speech.

Posted by Jim Lewis on January 10th, 2011

Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.

Nanotechnology powers rapid drug delivery by nanoparticles

Posted by Jim Lewis on December 30th, 2010

Catalytic nanomotors deliver nanoparticles containing drugs a thousand fold faster than do nanoparticles transported by Browninan motion.

Synergistic benefit of using nanotechnology to simultaneously deliver two anticancer agents

Posted by Jim Lewis on December 28th, 2010

Nanoparticles that deliver two anticancer agents simultaneously kill cancer cells more effectively than nanoparticles delivering the agents separately.

Surface properties of nanoparticles have profound effect on how cells respond

Posted by Jim Lewis on November 8th, 2010

Gold nanoparticles carrying nucleic acids into a cell must have the nucleic acids tightly linked via covalent bonds to avoid profound, unanticipated effects on gene expression.

Theoretical analysis of powering nanorobots with blood glucose and oxygen

Posted by Jim Lewis on November 4th, 2010

Hogg and Freitas provide a theoretical analysis of the power constraints when nanorobots rely entirely on ambient bloodstream oxygen and glucose and identify aspects of nanorobot design that significantly affect available power.

Today’s nanotech lets $400 camera see cancer cells

Posted by Christine Peterson on June 29th, 2010

Frequent Nanodot readers know that our main interest is longer-term nanotech, but sometimes what’s happening today gets pretty exciting as well.  A quick summary  of recent advances in nanotech used to fight cancer appears in a Computerworld piece by Sharon Gaudin; some excerpts: Rice University said yesterday that when the nanoparticles deliver dye to the cell, [...]

Join us at Singularity Summit, Aug. 14-15 on intelligence augmentation

Posted by Christine Peterson on June 16th, 2010

Many Foresight leaders and members will be gathering at this year’s Singularity Summit in San Francisco, expected to draw up to 1100 participants.  It’s a bit pricey, but it’s for a good cause and there are student and referral discounts plus discounts on the hotel rooms.  I can testify that this is a fun and [...]
