Enzyme-linked Immunosorbent Assay (ELISA) process is widely used for diagnosis, measurement of environmental materials, foods and so on, because of its extreme sensitivity for antigen-antibody reaction. This process, however, requires a long reaction time. We were able to shorten the reaction time required to less than 1 hour, which originally took several to more-than-ten hours, by widely enlarging the reaction area / volume with fabricating fine pillar arrays. Our process will show the possibility for instant diagnosis and instant medical treatment.Moreover, ELISA process also requires dilution or enrichment of samples beforehand when the concentration of samples is unpredictable because the measurable concentration range is narrow. By changing the reaction area from a vessel to a channel, our device had a larger measurable area which made it possible to detect drastically a wider range of sample concentrations.
