An aldol condensation reaction on oil-in-water (O/W) liquid interfacial plasmonic arrays was developed for sensing volatile aldehydes in alcohols by using an aromatic aldehyde as the probe for portable SERS assays. The detection limit was 10 -8 M. The substrate exhibited an RSD value of 6.9%, and the probe showed good selectivity to four common interferences.
