Publication number: 20150168334Abstract: A biosensor strip includes a strip body, a working electrode and a chemical reagent layer, wherein the strip body has a conductive portion and a reaction channel. The partial wall that forms the reaction channel is a partial or an entire surface layer of the conductive portion. The reaction channel has an opening that receives the sample fluid and an electrode hole. The working electrode is embedded in the electrode hole. The chemical reagent is configured in the reaction channel and generates an electrochemical reaction with the analyte. Therefore, after the sample fluid covers the reaction channel and the working electrode via the opening, the conductive portion and the working electrode on the wall of the reaction channel generate sensing currents and output the signals via the first and second signal output sides to determine an analyte concentration in the sample fluid.Type: ApplicationFiled: December 17, 2014Publication date: June 18, 2015Applicant: BIONIME CORPORATIONInventor: CHENG-TENG HSU

Patent number: 7438853Abstract: A photoelectrocatalytic method for detecting current that illuminates a photoelectrochemical electrode to generate a photocurrent and to magnify the current. Thereby, accuracy of the detection is increased. A photoelectrochemical detector used in the method has a base (10), a cover (20) pivotally mounted on the base (10) and a locking device attached between the base (10) and the cover (20). The base (10) has a top and a recess (12) defined in the top to accommodate a working electrode (50) with a photoelectrochemical inner lead (52). A spacer is clamped between the base (10) and the cover (20) to form a space over the inner lead (52). Multiple channels and a light hole (22) are defined through the cover (20) to communicate with the space. Therefore, the inner lead is illuminated through the light hole (22) to perform the photoelectrochemical method.Type: GrantFiled: May 19, 2004Date of Patent: October 21, 2008Inventors: Jyh-Myng Zen, Hsieh-Hsun Chung, Cheng-Teng Hsu, Hsueh-Hui Yang, Mei-Shin Chiou, Jun-Wei Sue
