Immunoassay-based rapid test kits are required in a point-of-care testing (POCT) which is defined as medical diagnostic testing at or near the site of patient care. They are widely required in various applications; for infectious diseases such as flu, HIV/AIDS, chlamydia and for monitoring health such as chronic diseases, pregnancy, cancers and so on. On the other hand, surface acoustic wave (SAW) devices have been widely used in wireless communications, mainly as frequency filters. Recently, more than twenty of SAW filters can be used in a smart phone. They can be mass manufactured easily and cost effective. We have developed a SAW-based immunosensor system which can detect immunoreactions of nanometer scale proteins such as antibodies and antigens. Since the SAW-based immunosensor system is small and quantitative and has advantages of ease of use and wireless connectivity, it is very suitable for POCT applications.
Dr. Hiromi Yatsuda was born in Sendai, Japan, in 1959. He received his B. Eng. and M. Eng. degrees in electrical engineering from the Technical University of Nagaoka, Niigata, Japan, in 1982 and 1984, respectively. In 1999, he received his Doctor of Engineering degree from Tohoku University, Japan. In 1984, he joined Japan Radio Co., Ltd., (JRC) Japan, where he was engaged in research and development on surface acoustic wave devices. His current research interests are on SAW-based sensors. He published a lot of technical papers on SAW technologies and he received the Best Paper Award 2008 from the Photopolymer Science and Technology. He has also provided over 50 patents in the world. In 2009, he joined OJ-Bio Ltd., Newcastle, UK, which is a joint company of JRC and a UK-based bio-company, ORLA protein technologies. He has developed SAW-based immunosensors. He is a biosensor project leader of research and development department of JRC.
