While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods.
Mike Treder from the Center for Responsible Nanotechnology (CRN) has reviewed Jürgen Altmann's book, Military Nanotechnology: New Technology and arms Control in the current issue of the Bulletin of the Atomic Scientists.
A Finnish group of researchers at the Low Temperature Laboratory of Helsinki University of Technology (TKK) have developed and fabricated a nanoscale heat transistor, and simultaneously the smallest refrigerator ever made.
Using a quantum dot plus an aptamer that doubles as a tether for the anticancer drug doxorubicin, a team of investigators at the Massachusetts Institute of Technology (MIT)-Harvard Center of Cancer Nanotechnology Excellence has developed a multifunctional nanoparticle that not only treats cancer but also images those tumors that have received drug therapy.
Nanoparticles made of metals such as gold or iron oxide show tremendous promise as contrast agents for molecular imaging, but turning promise into clinical utility requires adding tumor targeting molecules to the surfaces of these nanoparticles.
A tiny implant now being developed at the Massachusetts Institute of Technology (MIT) could one day help doctors rapidly monitor the growth of tumors and the progress of chemotherapy in cancer patients.
Using nanoparticles tagged with both a fluorescent label and a radioactive isotope of the element copper, a team of investigators at the California Institute of Technology has shown that targeting siRNA-containing nanoparticles to tumors increases tumor uptake rather than tumor localization.
Magnetic nanoparticles heated by a remote magnetic field have the potential to release multiple anticancer drugs on demand at the site of a tumor, according to a study published in the journal Advanced Materials.
A University of Arkansas physicist and her colleagues have examined dielectric susceptibilities of nanostructures and found novel, seemingly contradictory properties that may change how such materials can be used by scientists and engineers to build electronic devices.
