Research contents (Research key words)

We are developing the innovative diagnostics device which is usable in any hospital/clinic and home.  The device enable rapid (approx. 30 min) diagnosis of cancers from a small volume of specimen based on the detection of microRNA which have been attracting attention as a newly biomarker for cancer diagnosis.
We are also developing an original accurate analytical method of nano-particles such as exosome.

Keywords: Biodevice, Highly-integrated bio-microarray, Nano-diagnosis, microRNA, Exosome, Rapid molecular evolution
