摘要： An electrochemical test strip, an electrochemical test system, and a measurement method using the same are provided. The electrochemical test strip includes an insulating substrate, an electrode system formed on the insulating substrate, and an insulating layer formed on the electrode system. The electrode system includes a set of measurement electrodes, a set of identifying electrodes, and a resistive path having a predetermined resistance value. The set of identifying electrodes is made of metal material, and the resistive path is made of non-metal material. The set of measurement electrodes includes a reference electrode and a working electrode insulated from each other, and the set of identifying electrodes includes a first identifying electrode and a second identifying electrode connected with each other through the resistive path. The insulating layer covers a part of the electrode system, wherein a part of the electrode system not covered by the insulating layer forms a reaction region with a supply port. When a sample is injected into the supply port of the reaction region, the injected sample reaches the set of measurement electrodes and the set of identifying electrodes in sequence.

摘要： An immunochemical assay device is proposed. The immunochemical assay device includes a base member, a liquid-flowing layer disposed on the base member and a light-permissible member attached on the liquid-flowing layer. A gap is interposed between the light-permissible member and the liquid-flowing layer, wherein at least an immobilized substance is disposed on the surface of the light-permissible member facing the liquid-flowing layer. The immobilized substance binds to a specific ligand-receptor complex contained in a liquid sample to form an assay marker after the liquid sample has been added into the gap. The liquid sample flows in a microfluidic environment formed between the light-permissible member and the liquid-flowing layer and reacts with the immobilized substance to produce a colored assay marker on the light-permissible member. As the light-permissible member provides better transmission of light than previously known paper materials do, the assay marker can be easily detected by human eyes.
