Abstract: An objective of the present invention is to provide immunoassay microchips in which microstructures of beads having a sufficient reaction area were constructed within microchannels while suppressing flow path resistance, and to provide simple and highly-sensitive immunoassay methods for microsamples. The objective was achieved by immunoassay microchips comprising microchannels with microstructures arranged in at least a portion of the microchannels, the microstructures retaining microbeads uniformly dispersed in photo-cured hydrophilic resins, and the microbeads having a primary antibody immobilized on their surfaces, and by immunoassay methods using the microchips.

Abstract: A device for detecting a cholinesterase-inhibiting substance comprising a basal layer fixed at the bottom of a container, and a cholinesterase-containing reaction layer which is fixed on the basal layer, wherein the basal layer and the cholinesterase-containing reaction layer comprises a hydrophilic photo-crosslinkable resin.

Abstract: A detection device comprises a basal layer fixed at the bottom of a container therein, and a cholinesterase-containing reaction layer is fixed on the basal layer. A sample is added to the detection device, and the presence of a cholinesterase-inhibiting substance in the sample is visually determined through coloring reaction. For detecting an organophosphate agrichemical, the sample is brought into contact with an oxidizing agent on a column to convert it into the oxon form thereof.

Abstract: The seamless capsule of the invention is obtained by immersing in an aqueous fluid a two-layered seamless capsule comprising an inner layer comprising a suspension composition comprising a biocatalyst suspended in an oily substance and an outer layer comprising a shell composition comprising a water permeable substance. The seamless capsule of the invention, which has a pseudo three-layer structure of outer layer/oil layer/aqueous layer, is useful in that it is applicable to, for example, a bioreactor.
