Abstract: The present disclosure provides a biochemical test module. The biochemical test module includes a first reaction piece and a second reaction piece. The first reaction piece includes a first substrate; a first separator located on the first substrate and having a first flow channel exposing at least a portion of the first substrate; and a first cover covering the first separator. The first hole is connected with a first channel. The first reaction piece has a perforated structure penetrating the first cover, the first separator and the first substrate. The second reaction piece is disposed on one side of the first reaction piece adjacent to the first substrate and includes a second substrate; a second separator located on the second substrate and having a second flow channel exposing at least a portion of the second substrate; and a second cover covering the second separator and joined to the first substrate.

Abstract: A lactate dehydrogenase detector, which is used to detect a content of lactate dehydrogenase in a biological sample, comprises a substrate, an electrode assembly, a hydrophobic insulation layer, a cover and a reagent-containing membrane. The electrode assembly is disposed on the substrate and including a working electrode and a reference electrode. The hydrophobic insulation layer is arranged over the substrate and has a notch. The cover hoods the notch and cooperates with the substrate to form a sample channel accommodating the reagent-containing membrane. The reagent-containing membrane is made of materials selected from a group consisting of a lactic acid, nicotinamide adenine dinucleotide (NAD), diaphorase, and potassium ferricyanide. A bioelectrochemical reaction between the reagent-containing membrane and the lactate dehydrogenase induces an electrical signal variation in the electrode assembly, which indicates the content of the lactate dehydrogenase.

Abstract: A sensor for detecting glucose of rhizome plants comprises a substrate, an electrode module, a hydrophobic insulating layer and a cover. The electrode module is arranged on the substrate and includes a measurement portion and a connection section connected with the measurement portion. The hydrophobic insulating layer is disposed on the substrate to cover the measurement portion and the connection section and includes an opening revealing the measurement portion. The cover is disposed on the opening to form a specimen channel between the cover and the substrate. The measurement portion is arranged in the specimen channel. The electrode module includes a working electrode and a reference electrode opposite to the working electrode. The measurement portion of the working electrode has a first exposed region with an area of 4-6 mm2 in the specimen channel. Thereby, the present invention can detect the glucose concentrations of juice samples of rhizome plants.
