| Outline of Final Research Achievements |
The purpose of this research is measurement of the multi-parameters of a single cyanobacteria, whose size is approximately 2 um in diameter, with high-throughput under local microfluidic environment control. Here, we constructed the systems for mechanical characterization and measurement of oxygen consumption of the cell. As for the cellular mechanical characterization, we constructed the system which enables us to transport the target cell using optical tweezers, and to measure its mechanical properties using the microfluidic chip which has on-chip robots. Using the constructed system, we investigated the effect of osmotic pressure stimulation to cyanobacteria and its mechanical properties. As for the measurement of oxygen consumption, florescent dye is utilized as sensors whose florescent intensity changes with respect to oxygen concentration. We fabricated a stripe oxygen sensor into the microchamber, and successfully measured the oxygen concentration distribution of confined space.
