| Outline of Final Research Achievements |
In recent years, techniques for analysis from minority cells have been established. In this study, we aimed to establish a technique to manipulate, measure, and separate individual cells based on high-precision positional information for the purpose of application to analysis from minority cells. Therefore, we developed an in-situ direct manipulation, measurement, and separation system for single and minority cells by combining a two-fingered microhand that can handle two end-effectors dexterously and a highly functional nanopipette that can precisely control the local chemical environment. In addition, we have conducted experiments using this system on bacterial flagellar motors and animal cells, and confirmed that the system satisfies the required accuracy and contributes to solving unsolved problems of biological phenomena.
