Nanoscale “Glass” Bottles Could Enable Targeted Drug Delivery

Tiny silica bottles filled with medicine and a special temperature-sensitive material could be used for drug delivery to kill malignant cells only in certain parts of the body.
Researchers led by Younan Xia, professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, have studied the kinetics of autocatalytic reactions used to make colloidal metal nanocrystals suitable for catalytic, biomedical, photonic, electronic and other uses.

Researchers have developed a technique for producing platinum hollow nanocages with ultra-thin walls that could dramatically reduce the amount of the costly metal needed to provide catalytic activity in such applications as fuel cells. The image shows models of the (left) cubic and (octahedral) nanocages, whose surfaces are covered by atoms in square and hexagonal arrays, respectively. The yellow spheres correspond to platinum atoms while the green spheres indicate a small fraction of palladium atoms remain
Ultra-thin Hollow Nanocages Could Reduce Platinum Use in Fuel Cell Electrodes

A new fabrication technique could reduce the amount of platinum needed for fuel cell electrodes.
