In vitro osteoblast targeting ability of Apt-bioinspired MVs. Flow cytometry analysis of a rat osteoblasts, b rat dendritic cells, c whole bone marrow cells, d mesenchymal cells, and e osteoblast precursor 3T3 cells. All cell populations were counted. f Schematic illustration of the binding of Apt-bioinspired MVs with osteoblast through infrared thermal wave imaging based on the photothermal effect. g Infrared images of rat osteoblasts and dendritic cells incubated with Apt-bioinspired MVs, bioinspired MVs and PBS before and after washing, respectively. Source data of a–e and g are provided as a Source Data file
