Multi-scale silica structures serve as a sensing platform for enhanced biomolecule detection. The structures are fabricated by M. Khine and co-workers on page 568, by depositing a thin silica layer onto shrink-wrap, a pre-stressed polymer, film. The stiffness mismatch between the materials upon shrinking in an oven induces silica micro- and nanostructures that yield robust far-field fluorescence enhancements of attached biomolecules.
