Publication number: 20210405042Abstract: Disclosed are a one-pot biosensor and an immunoassay method using the same. The one-pot biosensor includes a photocatalyst substrate deposited with metal nanoparticles; and a reaction pad which is disposed on an upper surface of the photocatalyst substrate and includes a first binding material-fluorescent material complex specifically binding to a molecule to be detected, and the immunoassay method using the same. The one-pot biosensor may detect a target by once solution injection and has a size enough to be portable. Accordingly, since the one-pot biosensor can detect the target by only once solution injection without a washing step, because of a sensor platform capable of being easily used by an individual other than a diagnostic expert, it is predicted to be positioned as a means capable of confirming the health condition of the individual without seeing the doctor, such as a pregnancy diagnostic kit which has been currently commercialized.Type: ApplicationFiled: June 29, 2021Publication date: December 30, 2021Applicant: GIST (Gwangju Institute of Science and Technology)Inventors: Min Gon KIM, Ki Hyeun KIM, Eun Jung JO, Dong Gu HONG

Patent number: 11095398Abstract: A first electronic device according to various embodiments may select one of a plurality of representation matrices and one of a plurality of measurement matrices on the basis of a pattern and/or feature of data received from a sensor. The selection of the representation matrix and the measurement matrix may be performed on the basis of machine learning. Based on the selected representation matrix and measurement matrix, the first electronic device may adaptively compress at least a portion of the data. A second electronic device according to various embodiments may restore compressed data on the basis of the result of selecting the representation matrix and the measurement matrix. By dynamically selecting the representation matrix and the measurement matrix on the basis of machine learning, it is possible to reduce an error in the data restored by the second electronic device (e.g., a restoration error).Type: GrantFiled: April 28, 2020Date of Patent: August 17, 2021Assignee: GIST (Gwangju Institute of Science and Technology)Inventors: Eui Seok Hwang, Jun Ho Song, Yong Gu Lee
