Efficient field enhancement effects through plasmonic chemistry for ultrasensitive biosensing still face a great challenge. Herein, nanoconfinement engineering accumulation and synergistic are used to develop "plasmonic storms" strategy with high effect, gold nanoparticles (AuNPs) as active sites proof of concept because their distinctive localized surface plasmon resonance neighborly coupled electromagnetic field. Briefly, large number AuNPs selectively accurately stacked in the confined nanocavity bowl-like nanostructure an situ-synthesized strategy, which provides space strong coupling fields between these adjacent AuNPs, forming enhanced that is 3 orders magnitude higher than free AuNPs. The proposed nanoconfinement-engineered demonstrated by surface-enhanced Raman scattering (SERS) photothermal experiments theoretically visualized finite element simulation. Finally, colorimetric/SERS/photothermal immunochromatographic assay detect
