a Schematic illustration of the preparation process of Janus porous PLAM and self-assembly of MPN nanointerface. b SEM images of the Janus porous structure of PLAM scaffold (upper row: PLAM-P; lower row: PLAM-B) prepared with different PEG contents. c Average pore size of porous side and dense side, and the ratio of pore size of the porous side and the dense side. d Porosity of porous side and dense side. e WCA hydrophilicity measurement. f UV-vis absorption spectra. g FTIR spectra and h mechanical test of the pristine PLAM and PLAM-MPN scaffolds. n = 3 independent experiments, all data are shown as mean ± SD.
