1. A biosensor strip comprising:

  • a base plate layer defining a first strip end and a second strip end;

    a conductive layer being disposed on the base plate layer and partitioned into at least two electrode paths, wherein the at least two electrode paths are insulated from each other and the conductive layer comprises a conductive contact at the second strip end;

    a reagent containing layer being disposed on the conductive layer and comprising a first through hole that is located at the first strip end and for accommodating a reagent solution, wherein the first through hole exposes the partial area of the two electrode paths simultaneously and the reagent solution comprises matrix, redox mediator, enzyme, surfactant, and a buffer solution;

    a channel forming layer being disposed on the reagent containing layer and comprising a gap portion that is located at the first strip end, wherein the gap portion exposes the first through hole; and

    a cover layer being disposed on the channel forming layer and comprising a second through hole that exposes the partial area of the gap portion of the channel forming layer;

    wherein a sample channel is formed with the gap portion by placing the channel forming layer between the reagent containing layer and the cover layer and the second through hole is as a vent opening so as to increase the speed of a fluid sample getting into the sample channel.
