MEMBRANE STRIP SENSOR USING EXPANSION MEMBER

WIPO Patent Application WO/2017/115989

A1

A membrane strip sensor according to one embodiment of the present invention comprises: a support body; a sample pad attached to the upper surface of the support body to accommodate a liquid sample to be analyzed; a conjugate pad containing a primary reactant that specifically binds to an analyzed material contained in the liquid sample through the sample pad, the conjugate pad operating in conjunction with the sample pad; a reaction membrane for detecting whether an analyzed material exists in the liquid sample, the reaction membrane operating in conjunction with the conjugate pad; an absorption pad for absorbing the liquid sample for which the detection reaction has been completed, the absorption pad being located at the downstream side of the reaction membrane; and a secondary reactant pad located to be separate from the reaction membrane and connected to an expansion part that swells by means of the liquid sample accommodated in the sample pad, the secondary reactant pad being brought into contact with the reaction membrane by the swelling of the expansion part.
