PMNL (1 × 10⁶) were incubated with 0.5 mg mL⁻¹ PLGA-DY635[BRP-187] or Acdex-RhoB[BRP-187] NPs for the indicated time points at 37 °C. a Percentage of PMNL gated as positive due to the fluorescence signal of the dye-labeled NPs in the cell. b, c Mean fluorescence intensity (MFI) of NPs in the cell, measured by flow cytometry. For statistics analysis, a multiple t-test was used; p < 0.05 (*); p < 0.01 (**); p < 0.001 (***); n = 4
