Abstract: Disclosed is a multi-channel bio reactor with fluorescence detector which measures various bio-chemical materials using fluorescence analysis, and an on-line monitoring apparatus of it. The multi-channel bio reactor with fluorescence detector comprises a light source 10 for emitting excitation light; a light irradiation part 30 for irradiating the excitation light emitted from the light source 10; a sample receiving part 40 in which the excitation light irradiated from the light irradiation part 30 is irradiated on a sample and which has a plurality of walls 41 for receiving a sample containing a fluorescent material; and an optical detecting part 50 for detecting fluorescence emitted from the sample received in the wall 41 of the sample receiving part 40.

Abstract: The present invention relates to a multi-channel microbioreactor. More specifically, the present invention relates to a multi-channel microbioreactor having a number of wells in which an optical sensing membrane comprising a fluorescent dye and a bioconjugate, or a sensor material including a biomolecule conjugated to a fluorescent dye and a bioconjugate is formed. The multi-channel microbioreactor according to the present invention can be used for an in-situ optical detection of dissolved oxygen, carbon dioxide, pH, monosaccharides, polysaccharides, organic acids, alcohols, cholesterol, choline and xanthine, etc.
