Synthesis and characteristics of an intelligent responsive macrophage cell membrane-camouflaged MSNR drug delivery system. A Schematics showing the synthesis of FA-MSNR/LMDI@MP/MPCM. B TEM image of MSNRs. C TEM image of FA-MSNR/LMDI. D TEM image of FA-MSNR/LMDI@MP/MPCM. The inset image: macrophage cell membrane (indicated by the short arrows); MPEG-PAE (indicated by the long arrows). E TEM image of membrane detachment of FA-MSNR/LMDI@MP/MPCM in a weakly acidic environment. F UV–Vis spectroscopy of free DOX, free ICG, FA, MSNRs and FA-MSNR/LMDI. G Nitrogen adsorption–desorption isotherms of MSNRs and FA-MSNR/LMDI. H Pore size distribution plots of MSNRs and FA-MSNR/LMDI. I Changes in particle sizes of MPEG-PAE at various pH values. J Changes in zeta potentials of MPEG-PAE at various pH values. K Zeta potentials of MSNR and FA-MSNR/LMDI@MP/MPCM
