‘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.
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.
Novel biodegradable nanoparticles destroy membranes of drug-resistant ‘superbugs’ without harming blood cell membranes.
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.
A cover article in Time magazine portrays the Singularity, Ray Kurzweil, AI, life extension, and nanotechnology as “an idea that rewards sober, careful evaluation.”
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 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.
A new laser for nanotechnology could lead to more powerful microscopes, faster computers, and more efficient solar energy collectors.
Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.
Catalytic nanomotors deliver nanoparticles containing drugs a thousand fold faster than do nanoparticles transported by Browninan motion.
Nanoparticles that deliver two anticancer agents simultaneously kill cancer cells more effectively than nanoparticles delivering the agents separately.
Humanity+ @ Caltech: Redefining Humanity in the Era of Radical Technological Change is being streamed live.
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.
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.
Self assembly of aromatic dipeptide into nanospheres stiffer than Kevlar may make possible printing stronger, lighter body armor.

The Open Science Summit on July 29-31 in Berkeley is looking better and better. Topics include OpenPCR, DIY biology, open source hardware, brain preservation, synthetic biology, gene patents, open data, open access journals, reputation engines, crowd-funding and microfinance for science, citizen science, biohacking, open source biodefense, cure entrepreneurs, open source drug discovery, patent pools, tech transfer, and [...]
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, [...]
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 [...]
