Spreading and aspect ratio of HEK293 cells on soft (5 kPa) and rigid (2 MPa) surfaces after treatment with different concentrations (0, 0.1, or 1 μg/μL) of MNPs@SiO2(RITC). a Fluorescence images of cells with actin (green) and DAPI (blue) staining. b Cell spreading area and c aspect ratio. (n = 30 cells). NS: not significant. * P < 0.05, *** P < 0.001. Student’s t-test
