Characterization of the Apt-bioinspired MVs. a Schematic representation of the preparation of Apt-bioinspired MVs. b SEM image, c TEM image, d EDX analysis, and e AFM image of Apt-bioinspired MVs. f Height profiles along the white lines in graph e. g Photothermal curves of bare BPQDs and Apt-bioinspired MVs under NIR irradiation (1.0 W cm⁻²) after storing in PBS for 0, 1, 3, 5, and 7 days. PBS was used as the control. h Fluorescence images of dead/live cell staining after incubation with Apt-bioinspired MVs. Scale bars represent 150 μm. Hematological analyses of mice with indexes of (i) white blood cell count (WBC) and (j) red blood cell count (RBC). Blood biochemical analyses of mice with indexes of (k) total protein (TP), and (l) blood urea nitrogen (BUN). Data are means ± s.d. (n = 3), *P < 0.05, **P < 0.01, *** P < 0.001 (unpaired two-tailed Student’s t-test). Source data of  b–g, i–l are provided as a Source Data file
