| Abstract: | Based on connatural hierarchical micro/nanostructures of filter paper, convenient and efficient surface-enhanced Raman scattering(SERS) test strips were prepared by coating a silver layer on paper through simple physical vapor deposition(PVD). The limit of detection(LOD) over the SERS test strip is 10-10 mol/L with the Rhodamine 6G as probe molecule. Placing the test strips in airtight N2 atmosphere could remain the activity for a long time. |
