A new method for enhancement of luminescence from sol–gel based sensors is demonstrated, utilising the quenching effect and filtering effect of a gold film. Ruthenium (4,7-diphenyl-1,10-phenanthroline) 3 Cl 2 is encapsulated in a trimethoxysilane (

Summary Controversy over the role of antioxidants in cancer has persisted for decades. Here, we demonstrate that synthesis of the antioxidant glutathione (GSH), driven by GCLM, is required for cancer initiation. Genetic loss of Gclm prevents a tumor'
