Biological detection test piece and manufacturing method thereof

Abstract

The invention relates to a biological detection test piece and a manufacturing method thereof. The biological detection test piece comprises a detection unit and an auxiliary unit for generating capillary action. The detection unit comprises a substrate, at least one group of electrodes manufactured on the substrate by using a processing flow of a printed circuit board, leads connected with the electrodes and a photo-resistive layer covered on the substrate; and the auxiliary unit comprises a double-side adhesive layer and a hydrophilic layer which are provided with at least one sheet body respectively. The to-be-detected body fluid can quickly fill a reaction area formed by the photo-resistive layer by means of the processing mode of the printed circuit board and the use of the photo-resistive layer so that the to-be-detected body fluid can be uniformly and quickly reacted with reaction enzyme for detection.

Description

technical field [0001] The present invention relates to a biological detection test strip and its manufacturing method, in particular to a simple manufacturing method, and by virtue of the printed circuit board processing method and the use of the photoresist layer, the body fluid to be detected can be quickly filled with the photoresist layer The reaction zone, and the bioassay test piece which can react uniformly and quickly with the reaction enzyme for detection and its manufacturing method. Background technique [0002] The current biological test strips are mainly provided with a group of detection electrodes on the substrate, and a reaction zone is formed in the electrode area, in which reaction enzymes for specific detection items are placed. By putting the liquid to be tested in the reaction area, after mixing with the reaction enzyme, the electrochemical reaction will be carried out; and the corresponding electrochemical reaction signal can be transmitted to another...

AI Technical Summary

Problems solved by technology

First, placing the electrodes and wires on the bottom layer by pasting or printing cannot maintain consistent accuracy for the position of the electrodes and wires on the bottom layer, and it is impossible to change the position and shape of the electrodes, or control the effective length of the electrodes Second, during the manufacturing process, when the film used as the reaction zone is attached to the bottom layer, the manufacturer must precisely align the two, so the manufacturing process is very labor-intensive, and there will be glue overflow after lamination

If the two are not accurately aligned, it may cause the detection electrodes that should be exposed to be covered, resulting in differences between each piece or each manufacturing batch, or cover the condition of electrodes used to connect with external detection instruments; Will cause the test piece to lose its function or cause defective products
