We present an overview of the successes and challenges still faced in the detection of NO, O(2)(*-) and ONOO(-) in biological media. We provide a full discussion on the electrochemical analyses of each of these species and we summarise the significant research contributions towards the development of sensors for individual and simultaneous detection of(More)
In this work we report on the design, microfabrication and analytical performances of a new electrochemical sensor array (ESA) which allows for the first time the simultaneous amperometric detection of nitric oxide (NO) and peroxynitrite (ONOO(-)), two biologically relevant molecules. The on-chip device includes individually addressable sets of gold(More)
In this work, Fluorescent False Neurotransmitter 102 (FFN102), a synthesized analogue of biogenic neurotransmitters, was demonstrated to show both pH-dependent fluorescence and electroactivity. To study secretory behaviors at the single-vesicle level, FFN102 was employed as a new fluorescent/electroactive dual probe in a coupled technique (amperometry and(More)
