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.
