Fig. 12From: Intracellular trafficking and cellular uptake mechanism of PHBV nanoparticles for targeted delivery in epithelial cell linesEvaluation of nanoparticle degradation. HeLa and SKOV-3 cells were incubated with PHBV-Lysotracker® DND-99/nanoparticles for 4 h at 37 °C, then cells were fixed and observed through fluorescence microscopy. Objective: ×60 magnification.
