title: Electrochemical probing of photochemical reactions inside femtolitre droplets confined to electrodes.
abstract: Random ensembles of femtolitre-volume droplets containing redox active, photosensitive compounds immobilised on an electrode substrate permit photoelectrochemical studies within femtometric environments. Two chemical systems are described; the first is the N,N,N',N'-tetrahexyl-para-phenylenediamine redox-catalysed photochemical debromination of the anaesthetic reagent halothane; the second is the photoinduced electron transfer from excited chlorophyll a to vitamin K1, which has possible potential in the development of solar cells based on photosynthesis.
