A fully flexible plasmonic substrate was developed through a scalable, low-cost process that combines ultrathin PDMS membranes with micropatterned amorphous silicon. This configuration enables the stable and localized integration of gold nanoparticles, preserving their distribution during use. Thanks to the stability of the nanoparticles and the engineered design, the platform represents a versatile solution for flexible biosensing applications based on both fluorescence and Raman detection.
