Being involved in all stages of the journey from molecular beginnings to the first powering up of a chemical sensor device remains the philosophy of my research. In addition to designing new supramolecular calixarene complexing agents and applying these in Ion Selective Electrodes (ISEs), I currently synthesise new rhodamine fluorescent dyes which show selective colorimetric responses to physiologically relevant ions such as sodium and protons. As part of the search for materials to immobilise the molecules in-as necessitated by the sensor design-I investigate polymer chemistry and hydrogels. This organic synthesis, physical and analytical characterisation is complimented by my continued work with on-body sensors. Target analytes include ions in sweat. Such sensors may appeal to athletes or find use in the rehabilitation of cystic fibrosis sufferers or other areas entirely. I have investigated and published in the field of science education and remain interested in this area.
