| Outline of Final Research Achievements |
Development of multi elements analysis system for single cells is required to reveal the functions of trace metal elements in biological cells. In this study, a system of cell-handling technology based on microfluid mechanics were establish, and sample introduction was developed to inject the droplets containing a single cell into inductively plasma mass spectrometer (ICP-MS). The microfluid device for transport of cells was designed, and behavior of HeLa cells transported through a flow channel was observed by a microscope. The time-resolved ICP-MS with shortest time resolution of 10 μs was developed to measure the transient signals generated by injection of a single cell. Detection of the transient signals from 10 nm scale - silver nano particle was achieved.
