A rapid synthesis method of silica-coating Au nanorods (Au@SiO2 NRs) with manoeuvrable ultra-thin shell is introduced. The SPR of Au NRs is optimized to obtain large Raman enhancement. Based on this new development of SHINERS technique, we directly obtain enhanced signal in solution-based Raman tests of malachite green, giving a great potential to in-situ measurement.
