In this study, we investigated whether a bubble generated by photothermal conversion of plasmonic structure could function as a valve for micro flow devices. Many such valves close the flow path by compressing the path of the flexible material with a compressor. If bubble control technology by photothermal conversion can be studied, a mechanical compressors become unnecessary, and the flexibility of flow path design can be improved and the size can be reduced.
