Abstract
A biosensor comprises a space part for sucking and housing a sample formed of two upper and lower plates, the two plates being stuck together by an adhesive layer, the space part for sucking and housing the sample being constituted so as to be partially opened in the peripheral part and partially closed by the adhesive layer, and has a working electrode having at least glucose oxidase immobilized thereon and a counter electrode on the same plane of the plate.

19. A biosensor for measuring a concentration of glucose in a sample, the biosensor comprising:
-
a first substrate and a second substrate disposed over the first substrate, wherein the first and second substrates define a biosensor comprising a proximal end having a width and a distal end having a width, the distal end being configured for insertion into a biosensor reader, wherein the width of the distal end is greater than the width of the proximal end; a spacer layer disposed between the first and second substrates and defining an aperture along a first side edge of the biosensor configured to receive a sample fluid; a working electrode disposed on the first substrate; a mediator and a glucose dehydrogenase disposed on the working electrode; and a counter/reference electrode disposed on the second substrate, wherein the second substrate comprises a cut-out portion at the distal end to expose a portion of the working electrode disposed on the first substrate. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)

28. A method of determining a concentration of glucose in a subject, the method comprising:
-
contacting body fluid of the subject with a biosensor to generate an electrical signal, the biosensor comprising; a first substrate and a second substrate disposed over the first substrate, wherein the first and second substrates define a biosensor comprising a proximal end having a width and a distal end having a width, the distal end being configured for insertion into a biosensor reader, wherein the width of the distal end is greater than the width of the proximal end; a spacer layer disposed between the first and second substrates and defining an aperture along a first side edge of the biosensor configured to receive a sample fluid; a working electrode disposed on the first substrate; a mediator and a glucose dehydrogenase disposed on the working electrode; and a counter/reference electrode disposed on the second substrate, wherein the second substrate comprises a cut-out portion at the distal end to expose a portion of the working electrode disposed on the first substrate, determining the concentration of glucose in the body fluid using the generated electrical signal. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)

37. A biosensor device comprising:
-
a device body having a connector part and a control part, the connector part having input terminals; a biosensor comprising; a first substrate and a second substrate disposed over the first substrate, wherein the first and second substrates define a biosensor comprising a proximal end having a width and a distal end having a width, the distal end being configured for insertion into a biosensor reader, wherein the width of the distal end is greater than the width of the proximal end; a spacer layer disposed between the first and second substrates and defining an aperture along a first side edge of the biosensor configured to receive a sample fluid; a working electrode disposed on the first substrate; a mediator and a glucose dehydrogenase disposed on the working electrode; and a counter/reference electrode disposed on the second substrate, wherein the second substrate comprises a cut-out portion at the distal end to expose a portion of the working electrode disposed on the first substrate, wherein the input terminals of the connector part are electrically connected to the exposed portion of the working electrode when the biosensor is inserted into the connector part of the device body. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44)
