Abstract
We report the fabrication and characterization of a flexible, nanostructured surface-enhanced Raman spectroscopy sensor designed for integration in wearable optical devices. This sensor utilizes the bio-compatible material FlexDym®, which offers excellent flexibility and advantages in manufacturing. The nanostructures are embossed through a temperature and pressure-assisted molding process using a silicon master. The fabricated SERS structures exhibit significant enhancement in Raman signal detec-tion. This work advances state-of-the-art in flexible SERS and wearables.
