Silver nanoparticle-mesoporous oxide nanocomposite thin films: A platform for spatially homogeneous SERS-active substrates with enhanced stability

We introduce a nanoparticle-mesoporous oxide thin film composite (NP-MOTF) as low-cost and straightforward sensing platforms for surface-enhanced Raman Spectroscopy (SERS). Titania, zirconia, and silica mesoporous matrices templated with Pluronics F-127 were synthesized via evaporation-induced self-...
