Three disease biomarkers can simultaneously be detected at the attomolar level because of a novel surface‐enhanced Raman scattering (SERS) encoded silver pyramid sensing system. This newly designed pyramidal sensor with well‐controlled geometry exhibits highly sensitive, selective, and reproducible SERS signals, and holds promising potential for biodetection applications.
