AOTF-based remote sensor with sol-gel probe

Journal Article (Journal Article)

We report the development and application of a sensor using acousto-optic tunable filter (AOTF) and sol-gel probe technology. A pH-sensitive probe is used as a model sensing system with dextran derivatives of pH sensitive dyes doped into sol-gel thin films. We used a unique combination of pH-sensitive and pH-insensitive dual-label dye system. For optimization studies, the performance of these films as a pH sensing probe was evaluated using synchronous fluorescence detection. The performance of the a prototype AOTF-based monitor using a low-power argon laser as an ion excitation source was evaluated.
