Mostly,　surface-enhanced　Raman　scattering　(SERS)　sensors　used　the　Raman　characteristic　bands　concentrated　in　the　Raman　＂fingerprint＂　region　(500-1800　cm(-1)),　which　may　result　in　spectral　overlapping　interference.　The　study　of　the　response　in　the　Raman-silent　region　(10-500　and　1800-2800　cm(-1))　can　help　overcome　this　problem.　Hydrogen　sulfide　(H2S)　gas　causes　a　great　threat　to　human＇s　health,　but　its　low　concentration　in　the　airborne　species　is　a　challenge　for　sensitive　and　selective　detection.　Herein,　a　novel　low-wavenumber　(10-500　cm(-1))　SERS　sensor　for　H2S　gas　detection　has　been　developed　based　on　gold　nano-bipyramids　(Au　NBPs)　encapsulated　by　zeolitic　imidazolate　framework-8　(ZIF-8)　(Au　NBPs@ZIF-8).　The　sensor　takes　advantage　of　the　high　adsorption　capacity　of　ZIF-8　toward　H2S　gas　and　the　H2S-triggered　SERS　spectral　changes　in　the　low-wavenumber　Raman-silent　region.　A　clear　SERS　peak　of　Au-Br　at　similar　to　175　cm(-1)　generated　from　Au　NBPs@ZIF-8　showed　a　decrease　in　the　presence　of　H2S　because　of　the　competition　of　adsorption　sites　between　Au-S　and　Au-Br　bonds.　Furthermore,　Au　NBPs@ZIF-8　can　enrich　and　monitor　the　level　of　H2S　gas　with　high　efficiency　and　low　interference.　The　developed　sensor　has　a　detection　range　of　0.2　nM　to　20　mM　with　a　limit　of　detection　(LOD)　of　0.17　nM.　The　developed　sensor　had　been　applied　to　detect　the　H2S　gas　released　from　the　spoiled　fish　meat　with　high　selectivity.
