Micro-optodes: The role of fibre tip geometry for sensor performance

Publikation: Bidrag til tidsskriftKonferenceartikelForskningfagfællebedømt

Established sensors for fine scale measurements in natural environments are based on electrochemical measuring principles for e. g. oxygen and pH. The preparation of such electrochemical sensors is, however, a time consuming process. Based on the technical progress in the field of fibre optical measuring techniques many well-known chemical principles can now be used for the preparation of optical sensors, e.g. the oxygen measurement by luminescence quenching, and the pH-measurement with absorption based dyes. The use of optical fibres offers a high potential for miniaturisation of sensors [1]. For high spatial resolution measurements, the sensor chemistry has to be immobilised on the fibre tip, and the excitation and emission light has to be guided via the same fibre.
