Polishing teeth with silica nanoparticles produces much smoother surfaces than does polishing with larger silica particles, making it easier to remove harmful bacteria.
One of the main reasons that we are confident in the overall predictions of molecular manufacturing is that there are many pathways to it from current technology and using currently understood science. It is thus something of a milestone that we have arrived at a fork in the road about which there is room for… Continue reading Why the DMS debate is a good thing for nanotech
If you have a proposal on how nanotech could address a critical national and societal need, the National Institute of Standards and Technology (NIST) wants to hear from you.
Nanowerk News reports that an international nanotech collaboration of American and Korean scientists, funded by the Korean government, has developed multifunctional gold-coated nanowires that are designed to swim through the blood stream and attach to cancerous cells via antibodies against the cancer cells. Exposure to an electromagnetic field should heat the nanowires and destroy the… Continue reading Nanotechnology-produced wires to swim through blood, attach to, and kill cancer cells
A new nanotech method of DNA sequencing is 30,000 times faster than current DNA sequencing methods.
A method of depositing dense arrays of highly aligned carbon nanotubes on either rigid or flexible substrates promises transparent nanotech transistors for a variety of electronic applications.
The Allen Institute for Brain Science is using nanotech methods to map in which cells in the brain which genes are expressed.
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.
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.
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.
