Development of elemental technologies for fabricating the health care chip

To create the "health care chip", which is an intelligent micro analytical system to detect various human health markers from a small droplet of blood, we are now developing a measurement system of the markers in electroosmosis injected serum employing chemical sensors conjugated to the microcapillary made by a quartz plate. The complete system requires a painlessly collection of the blood by a needle, separation of serum from such small amount of blood, biocompatibility of the capillary inner surface and implementation of these technologies to the real health care chip. This paper reports recent studies regarding these elemental issues.
