Outline of Final Research Achievements |
I have developed a high-speed large droplet manipulation method that is an order of magnitude faster than conventional methods. Specifically, by precisely controlling the timing and position of the force applied to droplets, the developed method enables gentle and fast manipulation of fragile, large droplets, resulting in a 20-fold increase in the manipulation speed compared to conventional methods. Furthermore, I have demonstrated that microalgal cells can move freely in droplets larger than 100 pL, which is an advantage of our method. The survival rate of their microalgal cells and leukemia cells is increased as well as the antibody production of hybridoma cells. Furthermore, I have used it to isolate microorganisms with a slow growth rate, which only exist in about 2% of the population, confirming its usefulness and versatility.
