    • Sensors and methods for producing them are disclosed. A cavity is created and filled with a reagent that includes a conductive matrix, enzyme, catalyst, and binding agent, in a preferred embodiment. The cavity is substantially enclosed, leaving enough of an opening to allow the sample to enter. A portion of the material surrounding the cavity is preferably permeable to a substance useful for measuring reaction, but not to the reagent or the sample. Cavities that have the shape of a cone, conical frustum, pyramidal frustum, and right circular cylinder are given as examples. Other systems include a membrane that contains the sensor's active area and defines an internal volume of fluid, where the membrane or internal volume has a particular geometric relationship to the active area.
    • 公开了用于生产它们的传感器和方法。 在优选实施方案中,产生空腔并填充包含导电基质,酶,催化剂和粘合剂的试剂。 空腔基本封闭,留下足够的开口以允许样品进入。 围绕空腔的材料的一部分优选是可用于测量反应但不是试剂或样品的物质的透过性。 具有锥体,锥形截头锥体,金字塔形截头锥体和右圆柱体的形状的腔体作为示例。 其他系统包括包含传感器的活动区域并限定流体的内部体积的膜,其中膜或内部体积与活性区域具有特定的几何关系。
