Self‐supported gold aerogels of centimeter‐dimension and tunable ligament sizes are designed by Ran Du, Yue Hu, Alexander Eychmüller and co‐workers (article number 2100352) as new‐type 3D surface‐enhanced Raman scattering (SERS) substrates, featuring abundant hot spots distributed in 3D space. By investigating the ligament‐size‐effect on SERS performance, the optimized aerogel substrate manifests a high enhancement factor of up to 10 9 , outstanding misfocus tolerance (>300 μm), exceptional stability/reusability, and multiplex detection ability.
