| Outline of Final Research Achievements |
Probe beam deflection method was combined to dissolved oxygen-quenching of fluorescence and absorbance methods to develop a novel real-time detection method for monitoring materials movements across a plant surface. A laser probe beam was passed by a vicinity of a plant, and its deflection was monitored to obtain information on materials movements across the plant surface. Also, fluorescence of Ru-complex, which is quenched by dissolved oxygen, is also monitored to obtain the change of dissolved oxygen concentration. Furthermore, absorbance of the laser probe beam was monitored to get information on concentration change of chemical species which absorb the probe beam. Egeria densa and Ceratophyllum demersum L were used as model samples, and results of monitoring of their photo-synthetic and aspiration process showed that the novel detection could used for monitoring of materials movement across the plant surface, dissolved oxygen change near the plant surface.
