If most of the blood tests could be done with only a few drops of blood sample, you would not have to experience uncomfortableness of being taken plenty of blood for tests any more. We are carrying out the basic research to develop such a nano/ micro device for blood tests, which can detect the biochemical reaction in a flow tube as thin as a hair in diameter. We are trying to clarify the physicochemical phenomena in nano/ micro scale from a view point of applied mathematics, computer simulation and advanced molecular measurement system.

Recently, we have developed a novel method to produce the micro gel-beads containing cells using small channels so-called microchannels. It allows us to produce smaller and more uniform beads compared to the conventional methods. Injecting the oil and liquid containing cells into the microchannel with the width of two hundred micro-meter, droplets in micro meter scale containing cells are sequentially produced due to the liquid flow. The droplets transform into the gel-beads by chemical reaction at the downstream of the microchannel.

The beads containing cells are promising material in the field of the cell transplantation, which is safe and minimally invasive medical treatment compared to the conventional organ transplantation. The type I diabetes can be cured by transplanting the beads containing islets which generates insulin.

We are also working on various medical detecting systems applying nano-technologies and the computer simulation.
