a UV-vis spectra and b digital photo of MB before and after separation. c Filtration performance for different cationic dyes. d UV-vis spectra and e digital photo of MB@EY mixture before and after separation. f Filtration performance for cationic MB and different anionic dye mixtures. Data are collected to get average values (n = 5). g UV-vis spectra and TEM images of Au(−) NPs h before and i after separation. j UV-vis spectra and TEM images of Au(+) NPs k before and l after separation. The insets in h, i, and k are their corresponding size histograms.
