Optical Antigen-Antibody Reaction Measurement Instrument

DigInfo - http://movie.diginfo.tv Takuo Akimoto's research group at the Tokyo University of Technology is looking for a partner to commercialize a portable optical antigen-antibody reaction measurement instrument the group developed. The instrument uses surface plasmon resonance, a phenomenon in which the intensify of reflected light attenuates as the laser incidence angle changes, to measure antigen-antibody reactions simply. Antibodies are affixed to the tip of a glass sensor probe, which is 1.5mm in diameter and 50mm in length, and the probe tip is submerged in a measurement sample. The sample can be as little as 10 microliters. The instrument is 20cm long and 10cm wide, small enough to be carried around. The research group plans to make the instrument smaller and even more accurate and develop more applications for commercializing it.
