From: Endocytosed nanoparticles hold endosomes and stimulate binucleated cells formation
Nanoparticles were internalized by cells. a: SEM photographs were 30 nm Ps particles with ultrasonic or not. Utrasonic raised the monodispersion of 30 nm Ps particles obviously. b: Zeta potential of 30 nm Ps particels varied from -14 mV to -50 mV with ultrasonic. Potential detector checked the Ps 30 nm particles which were negative on surface. c: 30 nm Ps particles labelled with FITC entered the cell and were present in cytoplasm (red rectangle). d: 30 nm Ps particles gathered in large vesicle-like structures (LVLS) with time going along (white arrows)
