Abstract

A non-invasive glucose biosensor based on a paper disc immobilized with glucose oxidase (2.25 U disc-1) was developed to be used as a disposable patch on the commercially-available electrode (DS-710, Metrohm DropSens, Spain). The developed glucose biosensor system showed 0.01 mM of limit of detection in the linear range of 0.0 to 4.0 mM when the 20 μL sweat was used to measure a current at applied -0.155 V with a chronoamperometric (CA) method. Thus, this cost-effective and disposable glucose biosensor system can be expandable to other enzyme systems.


본 연구에서는 상업용으로 판매하는 DS-710 전극(Metrohm DropSens, Spain) 위에 산화 글루코스 효소 (glucose oxidase, 2.25 U disc-1) 를 고정화한 종이 디스크를 덮어 일회용 비침습 글루코스 센서를 제조하였다. 제조한 종이 글루코스 센서는 전기화학적 chronoamperometric(CA) 방법으로 약 20 μL의 땀에 포함된 글루코스의 양을 -0.155 V에서 선형구간 0.0-4.0 mM과 민감도 0.01 mM로 측정할 수 있었다. 따라서 본 연구에서 개발한 종이 글루코스 센서는 가격 경쟁력이 있고, 다른 효소에도 적용할 수 있는 확장력이 있는 비침습 바이오 센서이다.
