Outline of Final Research Achievements

In this research, a high sensitive biosensing system suitable for multi-scale and multi-analyte biomonitoring. On the basis of biosensensors formed on the soft polymers, we utilized an Os-HRP modified carbon electrode, on which lactate oxidase was immobilized, formed on the PET sheet for biomonitoring purpose. The sensing system was utilized in the monitoring of lactic acid contained in the sweat and CSF, respectively. As a result, both lactic acid was successfully monitored using our system. The level of lactic acid in the sweat after anaerobic exercise increased by 7.2 folds in comparison with that of normal situation. This indicates that the biosensor reflects the physiological situation of the human subject.
