Researchers Advance Sweat-Based Diagnostic Sensor Systems
A recent review published in the Journal of Pharmaceutical Analysis outlines how sweat can be collected and analyzed for clinical and field diagnostics, mapping devices, workflows, applications, and validation gaps. It reports advances combining microfluidic patches, wireless biosensors, and laboratory methods enabling trace detection of interleukins, glucose, β‑hydroxybutyrate, and drugs, but notes low concentrations, variable volumes, contamination, and the need for standardization and clinical validation.
Key Points
- 1Demonstrates microfluidic patches and biosensors detect ILs, glucose, β‑hydroxybutyrate and drugs at trace levels
- 2Highlights low concentrations, variable volumes, and contamination that undermine quantitative reliability and clinical adoption
- 3Calls for standardized collection, normalization, biomarker validation to enable reliable wearable and forensic applications
Scoring Rationale
Comprehensive peer-reviewed review with actionable standardization needs, but limited novelty and primarily vertical clinical scope.
