| Outline of Final Research Achievements |
This study aimed to develop a micromachine for cellular aggregate manipulation without damage. We proposed two types of micromachines based on pinching and flow controlling, respectively. Pinching type micromachine holds and release by using micro fingers which is pneumatically driven. 560μm×800μm micro fingers could catch and release a cellular aggregate of 200μm in diameter in a 96 micro-well-plate. Surface modification of micro fingers improved a success rate in releasing. Flow controlling type micromachine utilized a space between an inner wall of a micro well and micromachine itself. It could capture and release a cellular aggregate of 250μm in diameter in a 96 micro-well-plate.
Based on the results, improvement of throughput in manipulation is ongoing for further practical manipulator.
