Biocompatibility of empty and FP- loaded NLC: time-dependent experiments. Bronchial epithelial cells (16-HBE) were cultured in the presence and in the absence of FP, NLC and FP-loaded NLC (10⁻⁸M) for 48 (A) and 72 (B) hours and cell necrosis and cell apotosis were assessed using the PI/Annexin V method by flow cytometry. Representative dot plots were shown.
