High-precision imaging revealed what holds on the smallest light responsive gold chain

Manufacture of chemical sensors and catalysts based on gold nanoclusters gained new light from recent cutting-edge research. Chemists at the University of Jyväskylä, Finland and the University of California succeeded in determining the atomic precise structure of a chain of gold nanoclusters attached to each other. The researchers revealed the disulfide-bridging bond between the bound nanoclusters. Linked gold nanocluster structures advance our understanding of the optical and electronic response of these systems which hold future perspectives in nanoelectronics and bioimaging.
