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.
From the February 2009 issue of the “science is culture” publication Seed magazine, not yet online: Hypothesis: Civil Nanotechnology Starting in 2009, nanotech-based sensing will enable a level of environmental monitoring that could help reduce pollution tremendously. Such devices could be of immense benefit to the environment, but unfortunately, without careful attention they will trigger… Continue reading Civil nanotechnology: Open source sensing in Seed magazine
A newly discovered repulsive quantum mechanical force could be useful for nanotech applications by enabling a type of quantum levitation.
An open-access review article describes how a layer of nanoparticles of different sizes, compositions, and shapes enhances the efficiency of thin-film solar cells.
Nanotech could make possible the controlled release within the patient of up to four different drugs by irradiation with different wavelengths of near-infrared radiation.
Research on the interactions between carbon nanotubes and neurons shows that electrical phenomena in nanotubes may lead to engineering interactions between nanomaterials and neurons.
Polishing teeth with silica nanoparticles produces much smoother surfaces than does polishing with larger silica particles, making it easier to remove harmful bacteria.
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
