Abstract
A biosensor (1) includes a capillary (3) having a channel (30) with an inlet port (30a) for taking in a sample liquid, a membrane (8) for promoting the movement of the sample liquid through the channel (30), and a reaction part (7) containing a reagent that reacts with a component to be tested in the sample liquid whose movement has been promoted by the membrane (8).
Claims16
A biosensor, comprising:
- a capillary having a channel with an inlet port for taking in a sample liquid;
- a membrane for promoting movement of said sample liquid through said channel;
- and
- a reaction part containing a reagent that reacts with a component to be tested in said sample liquid whose movement has been promoted by said membrane.
A method for manufacturing a biosensor which comprises a capillary having a channel with an inlet port for taking in a sample liquid, a membrane for promoting movement of said sample liquid through said channel, and a reaction part containing a reagent that reacts with a component to be tested in said sample liquid whose movement has been promoted by said membrane;
- the method comprising the steps of:
- forming a working electrode and a counter electrode in an elongate configuration on an insulating base;
- forming an elongate reaction part intersecting said working electrode and said counter electrode;
- laminating an elongate membrane on said reaction part;
- providing a pair of walls along longitudinal edges on both sides of said reaction part and said membrane;
- and
- forming a capillary by forming a cover bridging said pair of walls.
