The sponge pores decorated with Au nanoparticles could effectively capture and concentrate microplastics in the pores from aquaes sample. Interestingly, the adjustable size of the sponge could allow the distance between the “hot spots” on the substrate surface to be controlled, hence controlling the SERS signal intensity. |
