Characterising gold nanoparticles at atomic resolution might improve our understanding of the catalytic activity of these materials, according to an international team. These researchers (Kornberg et al) have now demonstrated that it is possible to use electron microscopy to obtain data on at least one gold cluster of greater than 1 nm diameter and to […]
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. Scientists can now explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs.
With a chemical “trick,” scientists have succeeded in isolating a stable gold carbene complex. Chemists have now created the basis for directly examining the otherwise unstable gold-carbon double bond. They explain that highly reactive gold carbene molecules play an important role in landmark catalyzing processes taking place at high speed.
