A wearable sweat sensor chip based on surface-enhanced Raman spectroscopy is developed. The plasmonic core of the chip, obtained by depositing silver nanowires on a PTFE porous membrane, permits the direct and label-free detection of urea and lactate at physiological concentration in combination with the evaluation of sweat pH in the range between 4 and 9.

Abstract
A wearable sweat sensor chip based on surface-enhanced Raman spectroscopy is developed. The plasmonic core of the chip, obtained by depositing silver nanowires on a PTFE porous membrane, permits the direct and label-free detection of urea and lactate at physiological concentration in combination with the evaluation of sweat pH in the range between 4 and 9.File in questo prodotto:
