Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces. [PDF]

Small
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.
