From: Hedgehog artificial macrophage with atomic-catalytic centers to combat Drug-resistant bacteria
a SEM and b HR-TEM images of Fe-Art-M. c N2 adsorption/desorption isotherms and corresponding surface areas of Art M, Fe-Art M, and V-Art M. d XRD spectra of Art M, Fe-Art M, and V-Art M. e The HAADF-STEM images and corresponding EDS mapping of Fe-Art M. f SEM images of the bacterial capture capability of Fe-Art M when incubated with MRSA. g The calculated number of MRSA captured by different Art Ms in e (n = 3 independent experiments, data are presented as mean ± SD). The inset of g is a magnified captured bacteria by the spikes. h Calculated live/dead bacteria ratio based on the fluorescence results, pH = ~5.8; data were obtained from three fluorescent microscopy images with scope 1 mm × 1 mm, and presented as mean ± SD. 3D reconstructions from confocal laser scanning microscopy (CLSM) images of i V-Art M and j Fe-Art M when treated with MRSA at the same condition as h. h p values are assessed by unpaired Student’s two-sided t-tests. Experiments were repeated independently (a, b, e, f, i, j) three times with similar results. d a.u. indicates the arbitrary units. Source data are provided as a Source Data file.
