BioQuant Seminars: „Beyond Human Technology“ Opens a New World in Bio Science
24. August 2017 @ 16:00 - 17:00
Makoto Kaneko – „Beyond Human Technology“ Opens a New World in Bio Science
Dept. of Mechanical Engineering, Graduate School of Engineering Osaka University
Hosted by Motomu Tanaka.
This talk begins by explaining what is “Beyond Human Technology”. Knowing of the limitation of human perception and action, we show how to design an artificial system leading to “Beyond Human” by utilizing two kernel components, an online high speed vision and a high speed actuator where both speeds are several hundred times faster than human eye and muscle, respectively. As for a test bed, we designed and developed a fast and fine cell manipulation system with the maximum frequency of 130Hz and the resolution of 240 nanometers (2015, Monzawa and Kaneko, Biomicrofluidics). While observing the recovery characteristic of Red Blood Cell (RBC) after passing a narrow microfluidic channel, we found an interesting behavior where the recovery time constant strongly depends upon the loading time in the narrow microfluidic channel (2017, Ito, Kaneko, and Tanaka et. al., Scientific Reports). As another application example of the cell manipulation system, we introduce “Cell Stress Test” where it was shown that a RBC eventually loses recovery characteristic after imparting mechanical stress with several hundred times (2014, Sakuma and Kaneko, Lab- on-a-Chip). All topics will be explained together with video demonstration.
