Assuming the realization of a ubiquitous human healthcare system in the near future society, I performed the research of realizing principal functions of high-end cell analyzer like a flow-cytometer into a minute total analysis system (TAS) chip which consists of both micro fluidic channels and light waveguides. Our fundamental concept of realizing this novel TAS utilized for the healthcare system is founded on the technologies of resin-based light waveguide that is already applied to a high-speed signal processing circuit board. Carefully fabricating minute fluidic channels on a surface of waveguide-formed resin layer could make it possible to properly and precisely illuminate cells or particles running along a fluidic channel, and finally, through a series of experiments of detecting extremely weak scattered light, we could successfully confirm fundamental functions to evaluate optical properties of a pseudo-cell, utilizing trial-manufactured resin-based TAS chips.
