The　recently　reported　shell-isolated　nanoparticle-enhanced　Raman　spectroscopy　(SHINERS)　is　considered　as　the　next　generation　of　advanced　spectroscopy　for　its　surface　and　molecular　generality.　With　the　aim　to　utilize　the　virtues　of　shell-isolated　strategy　and　advance　the　SHINERS　technique,　we　introduce　a　silane-based　rapid　synthesis　method　of　silica-coating　Au　nanorods　(Au@SiO2　NRs)　with　manoeuvrable　ultra-thin　shell　and　tunable　SPR.　The　results　demonstrate　that　the　SPR　of　Au　NRs　could　be　optimized　to　obtain　large　Raman　enhancement　using　either　633　nm　or　785　nm　laser.　Differing　from　previously　reported　Au@SiO2　NRs　synthesis　method,　we　can　tune　the　silica　shell　thickness　within　several　nanometers　to　maximize　the　Raman　signal　while　effectively　eliminating　the　exterior　interference.　And　this　advanced　synthesis　method　has　also　significantly　reduced　the　silica-coating　time　from　one　day　to　ca.　1　h.　This　method　as　a　new　development　of　SHINERS　technique　has　successfully　got　enhanced　signal　in　solution　Raman　tests　of　malachite　green,　giving　a　great　potential　to　be　extended　to　in-situ　measurement　for　daily　life　detection.　Copyright　©　2013　John　Wiley　&　Sons,　Ltd.
