Nanotechnology could introduce flaws into carbon nanotubes to build circuits

Computational nanotech studies have shown that deliberate introduction of structural defects at specific sites in carbon nanotubes can guide electrons along specific paths, providing a way to fabricate complex electronic circuits from nanotubes.

Targeting highly metastatic melanomas with nanotechnology

Using a promising nanotech approach to deliver the RNA molecules, a type of nanoparticle described as a neutral liposome was administered to mice bearing melanoma tumors and found to cause a significant decrease in tumor growth and in the number of metastatic tumor colonies.

Tracking single molecules in living cells using nanotechnology

Previously unknown spectral properties of carbon nanotubes functionalized with DNA have been exploited to create nanotech sensors that can simultaneously detect several different substances, in real time, within living cells, to single molecule sensitivity.

Study of the FDA's ability to regulate nanotechnology-based dietary supplements to be released

How well prepared is the FDA to regulate nanotech products? Perhaps not very well, at least in the area of dietary supplements.

Tunneling electrons could power nanotechnology

Molecular dynamics simulations show that electron tunneling through nanoscale rotary motors based on carbon nanotube shafts may enable nanotech motors to rotate more than a million times faster than their biological counterparts.

Nanotechnology advance toward individualized cancer treatments

The effectiveness of treatment with multifunctional nanoparticles was studied using human breast tumors grown in rats lacking an immune system so that the variation in the effectiveness of treatment could be compared among individual breast tumors.

NanoPhobia … Phobia

In an interesting coincidence and counterpoint to Jim’s Nanophobia post this morning, I ran across the following on Nature News: Fearing the fear of nanotechnology. It is, surprisingly perhaps, by our old friend Richard Jones. The thrust of the article is that a study in Nature Nanotechnology seems to show that the public’s reaction to… Continue reading NanoPhobia … Phobia

Uncertainty over safety of nanotechnology in consumer products

It is not clear that there is any real danger from the nanotech products currently in use, but neither is there convincing proof that all are safe.

Foresight — with Peripheral Vision: Nanotech & AI forecast from Josh Hall

Josh Hall, author of Nanofuture: What’s Next for Nanotechnology, sends this message to Nanodot readers: Dear Foresight members & friends, It’s the time of year when many of you are renewing your Foresight memberships, and helping us meet our $30,000 goal for our Challenge Grant by December 31: https://foresight.org/challenge I believe that the next decade… Continue reading Foresight — with Peripheral Vision: Nanotech & AI forecast from Josh Hall

A better raincoat through nanotechnology

A nanotech technique that can coat any number of common fabrics with a layer of silicone nanofilaments appears ready to produce durable, completely waterproof clothing.
