Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The invention uses the electrochemical principle to apply the biosensor to the detection of physiological parameters, and can be used to qualitatively or quantitatively measure specific substances in biological samples. The sensor is composed of various materials. It is built on a substrate or carrier, and electrode wires are printed on the substrate. The number of electrodes can be two levels, working electrode and counter electrode, or multi-level electrodes. A layer of insulating material is printed on the substrate where the electrodes are printed, and this layer of insulating material defines the reaction area of ​​the sensor reaction area; on the substrate with the printed reaction area, the pad layer and the appropriate groove are printed again around the periphery of the reaction area, There is an opening near the end...

Abstract

The invention relates to a manufacturing method of a biosensor and provides the feasibility of a printing process of an electrochemical sensor, the convenience of integral manufacturing and the integrity of integrated printing. The biosensor disclosed by the invention is configured on a base plate, and a two-electrode or multielectrode wire is printed on the base plate, wherein two electrodes include a reference electrode and a working electrode. One layer of insulating material is printed on the base plate printed with the electrodes, and the response area of a response zone of the sensor is defined by the insulating material. On the base plate printed with the response zone, a raising layer and a proper groove are printed again around the periphery of the response zone, so as to guarantee the space of the response zone and make sure that response liquid smoothly enters and air is smoothly exhausted. The following manufacturing procedure comprises the step of spraying a response solution in the response zone. One layer of hydrophilic material covers and is abutted on the raising layer and the groove, and additionally, the space in the response zone is configured. One layer of hydrophobic material is abutted on the uppermost layer to match a transparent observation window in the upper response zone.

Description

technical field [0001] The invention belongs to the field of fabrication technology, and relates to the fabrication, feasibility, convenience and integrity of electrochemical sensors. More precisely, the fabrication of the electrochemical sensor provides the feasibility of the printing process, the convenience of integrated fabrication and the integrity of integrated printing. Products are used in electrochemistry, including but not limited to micro-current sensors and micro-current detection technology. Background technique [0002] Biosensors for electrochemical methods, or more commonly referred to as "test paper", use a non-conductive substrate or carrier, on which a circuit is printed or etched, and the circuit includes at least: a working electrode, a counter electrode In the electrochemical circuit, there is a fixed-area reaction area on the frame, and there are fixed-area working electrodes and counter electrodes in the area, and the relative distance between the tw...
