Publication number: 20240077417Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.Type: ApplicationFiled: July 11, 2023Publication date: March 7, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jin Hwa RYU, Soocheol KIM, Hyunseok KIM, So Yung PARK, Hoe-Sung YANG, Kang Bok LEE, Kwang-Soo CHO, Kyu Won HAN

Patent number: 11883406Abstract: The present invention relates to a method for producing an alginic acid-folic acid conjugate, an alginic acid-folic acid conjugate produced thereby, and a pharmaceutical composition containing the same. According to the method of producing an alginic acid-folic acid conjugate using a carboxy-protecting group and a leaving group, the hydroxyl group of alginic acid forms an ester group with the carboxyl group of folic acid. Thus, the alginic acid-folic acid conjugate may clearly distinguish cancer cells from normal tissue by more effectively targeting cancer cells than a conventional alginic acid-conjugated folic acid in which the amine group of folic acid is covalently bonded to the carboxyl group of alginic acid. Accordingly, the alginic acid-folic acid conjugate may be effectively used for precise diagnosis and efficient surgical resection of cancer lesions.Type: GrantFiled: February 1, 2022Date of Patent: January 30, 2024Assignee: SEOUL NATIONAL UNIVERSITY R&DB FOUNDATIONInventors: Kang Won Lee, Sa Ra Lee
