Implication

This research demonstrates a flexible microelectrochemical sensor's ability to detect uric acid and tyrosine in sweat, indicating potential for noninvasive health monitoring.

Key Points

The developed sensor achieved a sensitivity of approximately 9 mAM-1 for tyrosine and 1 mAM-1 for uric acid, demonstrating impressive performance.
The limit of detection (LOD) for uric acid was found to be 2.9 μM, while tyrosine had an LOD of 12.4 μM, indicating high detection capability.
The laser-induced graphene (LIG) sensor maintained stability across various pH levels, ensuring reliable performance in different conditions.
Selectivity tests confirmed that the sensor could distinguish target analytes in the presence of common sweat interferents, highlighting its robustness.
