Patent number: 11045119Abstract: The present disclosure relates to a biosensor for measuring glucose in a biological sample, which contains a filter unit formed of a cytoplasmic membrane, which allows selective permeation of glucose in a biological sample. The biosensor of the present disclosure, which contains the cytoplasmic membrane filter unit allowing selective permeation of glucose in the biological sample, exhibits high glucose detection sensitivity as compared to the commercially available blood sugar measuring sensors and also exhibits high glucose detection specificity despite the addition of signal-interfering substances such as fructose, xylose, maltose, cysteine, ascorbic acid, uric acid, galactose, etc. In addition, because he cytoplasmic membrane filter unit contained in the biosensor for measuring glucose of the present disclosure is not significantly affected by the moisture in the air, it can be applied to various products such as a disposable blood sugar test strip or an attachable or implantable glucose measuring device.Type: GrantFiled: July 10, 2018Date of Patent: June 29, 2021Assignee: Korea University Research and Business FoundationInventors: Dae Sung Yoon, Do Hyung Kwon, In Su Kim, Gyu Do Lee, Dong Tak Lee, Sang Won Lee

Publication number: 20210116448Abstract: The present disclosure relates to a method for measuring fibrinogen concentration in a blood sample, which enables measuring of the concentration of the fibrinogen protein present in a blood sample from the human body. The method for measuring fibrinogen concentration of the present disclosure is convenient because an enzyme is not used. In addition, an error due to a factor affecting factor affecting in-vivo enzyme activity does not occur and measuring time is decreased since measurement for reference plasma is unnecessary. Therefore, the method achieves superior accuracy, precision and reproducibility as compared to the existing technologies and can be usefully employed for measuring fibrinogen concentration in a blood sample.Type: ApplicationFiled: April 8, 2019Publication date: April 22, 2021Applicant: KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATIONInventors: Dae Sung YOON, In Su ` KIM, Do Hyung KWON, Dong Tak LEE, Sang Won LEE, Gyu Bok LEE, Gyu Do LEE
