Outline of Final Research Achievements

A property analysis of 12A11 antibody, which is an anti-norovirus antibody that we developed, was performed, and it was confirmed that the antibody reacted to several different genotype noroviruses. We showed that it was possible to detect approximately 100 virus-like particles of norovirus existing in the detection area of a fluorescent-detection-type biosensor utilizing a surface plasmon resonance excitation layer of aluminum, in which the antibody and a quantum dot fluorescent dye were used. It was also confirmed that a time-resolved fluorescence imaging method can successfully distinguish noises emitted from sensor chip substrates from signals of the fluorescent dye. The sensitivity of the sensor was improved quadruple by introducing the time-resolved fluorescence imaging.
