A wash-free and direct SERS platform for non-invasive kidney health monitoring via multiplexed urinary biomarker detection.
Routine monitoring of urinary biomarkers is critical for the early diagnosis of chronic kidney disease (CKD), yet conventional surface-enhanced Raman scattering (SERS) methods often require tedious washing steps to remove unbound reporters. Herein, we report a wash-free, multiplexed SERS chip designed for the spatially...
