The CLSM images. The HeLa cells, MG-63 cells, MCF-7 cells, and MC3T3-E1 cells incubated with HCPT-loaded NSs ([HCPT] = 1 mg/mL), HCPT-loaded NRs ([HCPT] = 1 mg/mL), and NDs ([HCPT] = 1 mg/mL) for 0.5 h (a), 1.5 h (b), and 4.5 h (c) at 37 °C, respectively. All images were taken under identical instrumental conditions and presented at the same intensity scale. All scale bars are 25 μm
