| Research Abstract |
To realize new fluidic devices using soap film, we have investigated techniques for the transport of molecules in and on soap film. Viscous soap films optimized for stability can last for several days and allow us to transport analyte molecules involved in droplets on the films, not dispersed in the film. The droplets on the film are stable for several minutes without coalescing with the film and can flow and spread freely. It has been shown that the droplet containing polyvalent electrolytes on the film can be transported with a constant mobility by an electric field and separated by the valence.
