In new variation of ways to use nanotech to treat cancer, scientists have shown that using a scorpion toxin to target nanoparticles to brain cancer cells depletes the amount on the cancer cell surface of a protein required to make the cells invasive. From the National Cancer Institute’s Alliance for Nanotechnology in Cancer “Toxin-nanoparticle combo… Continue reading Targeting brain cancer cells with nanotechnology makes them less invasive
Now comes a method to prepare high-density arrays of perfectly aligned, 95%-pure semiconducting SWNTs.
Following up on recent posts about concern in the insurance industry and in Congress about risk management practices for (current and near-term) nanotechnology, David Forrest passes along this news of recent action at EPA: The EPA has published their Interim Report on the Nanomaterials Stewardship Program and continues to invite comment for the final version.… Continue reading EPA encourages input to develop risk management practices for nanotechnology
Cambridge University scientists announced a way of making long thin carbon nanotubes link together to form a material that might suffice to built a space elevator.
Last September we wrote that one insurer would “no longer insure against bodily injury, property damage, or personal and advertising injury related to the actual, alleged, or threatened presence of or exposure to nanotubes or nanotechnology in any form.” Now Christine Peterson passes along this item from Rhitu Chatterjee writing in the American Chemical Society… Continue reading Insurance industry looking for more data on nanotechnology risks
In light of the call for open-source sensing arising from nanotech-based environmental monitoring, it is interesting to note this recent progress in building a nanotech-powered biosensor powered by molecular motors.
An international team of investigators has demonstrated in mice a nanotech method of orally delivering an anticancer therapy that would normally have to be delivered by injection.
The Project on Emerging Nanotechnologies, via AAAS EurekAlert, brings us an update on federal efforts to address the potential environmental, health and safety (EHS) risks posed by engineered nanomaterials. “New House bill addresses need for more risk research, oversight“: The House Science and Technology Committee [on January 15] introduced legislation that highlights the growing attention… Continue reading Nanotechnology oversight issues moving forward in Congress
Having demonstrated a year ago an effective nanotech method for shutting down specific gene expression in a mouse model of colitis, a team of researchers at Tel Aviv University is preparing to test this method in clinical trials for blood, pancreatic, breast and brain cancers.
A method that eliminates metallic single walled carbon nanotubes from mixtures leaving fully functional semiconducting SWCNTs may open the way for various nanotech applications that require pure semiconducting SWCNTs.
