Encapsulating magnetic iron oxide nanoparticles within a silica shell has yielded a new multifunctional nanoparticle that has the potential to image, target, and treat tumors with water-insoluble anticancer drugs.
A research team at the University of Texas M.D. Anderson Cancer Center has found that pretreating tumors with gold nanoparticles and near-infrared radiation dramatically improves the response of tumors to radiation therapy.
Taking a cue from the semiconductor industry, a team of investigators at Stanford University has developed a method of producing unlimited quantities of highly magnetic nanoparticles suitable for use as magnetic resonance tumor imaging agents.
Dendrimers are spherical polymer nanoparticles that have shown promise as targeted anticancer drug delivery vehicles. Iron oxide nanoparticles have already demonstrated the ability to image tumors and metastatic lesions. Now, researchers at the University of Michigan have combined the two, producing a layered nanoscale construct that targets and images tumors in animal models of human cancer.
On January 28th, 2008, EPA launched the Nanoscale Materials Stewardship Program (NMSP). To date EPA has received three submissions for nanoscale materials under the basic program. EPA has also received commitments from ten additional companies to submit data on nanoscale materials under the basic program. Thus far no one has signed up to participate in the in-depth portion of the NMSP.
In order to monitor how far an HIV infection has progressed, the number of immune cells - lymphocytes - must be counted. Researchers at the University of Twente have developed a method that neatly arranges the antibodies that bind to these immune cells on a 'molecular printboard'.
Biodetection Technologies is an internationally recognized event for experts in detection and identification of biological and chemical threats. Delivering this year's opening keynote address will be Robert Hooks, the Deputy Assistant Secretary for WMD and Biodefense from the U.S. Department of Homeland Security.
Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation.
Researchers at the NSF Nanoscale Science and Engineering Center for High-rate Nanomanufacturing (CHN) at Northeastern University, with partners UMass Lowell and University of New Hampshire, have discovered an innovative technology that will have a tremendous impact on the nanotechnology industry.
