Abstract

original image

Film star: The synthesis of mesoporous Pt–Au alloy films of varying composition by using a square-wave potential program is described. A Pt51Au49 alloy film exhibits superior performance for the detection of glucose than those reported previously. The activity was found to be strongly dependent on the synergistic effects of the mesoporous structure and the Pt–Au alloy surface.
