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.
A new antibacterial material that has potential for cutting hospital acquired infections has been developed by scientists. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light — even under modest indoor lighting. And in a first for this type of substance, it also shows impressive […]
