High-performance flexible surface-enhanced Raman scattering substrate based on the particle-in-multiscale 3D structure

Recently, multiscale three-dimensional (3D) structures consisting of micrometer-scale structure and nanometer-scale structure have received some attention from scientists in the field of surface-enhanced Raman scattering (SERS). In this work, micrometer-scale grating structure and nanometer-scale zi...

The optimized particle-in-multiscale 3D substrate (PDMS/grating/ZnO NSs/Ag NPs) presents high sensitivity with an ultralow limit of detection of 1 × 10−11 M and a high enhancement factor of 7.0 × 108 for Rhodamine 6G (R6G) as the probe molecule.
