[Display omitted] •Au@hg-C3N4 hybrids were fabricated as a dual-mode matrix of SERS and SALDI-MS.•The holey structure enhances matrix enrichment and prevents Au NPs agglomeration.•Au@hg-C3N4 matrix exhibits high sensitivity and superior reproducibility for l-cys.•The matrix reliably detects l-cys an...
