A Wearable Microfluidic Sweat‐Patch Pilot Study for Detecting Breast‐Cancer Proteins CEA and PIP/GCDFP‐15

Advanced Healthcare Materials, EarlyView.
A passive capillary‐driven microfluidic patch standardizes noninvasive sweat collection from the axilla and chest during exercise. Paired sweat and capillary blood samples enable laboratory ELISA analysis of CEA and PIP. CEA is detectable but often below quantification limits, while PIP remains undetectable in sweat.
