Purpose. The objective of this study was to evaluate the extent and mechanism of uptake of fluorescent chitosan nanoparticles by the A549 cells, a human cell line derived from the respiratory epithelium. Methods. Covalent conjugation with fluorescein-5-isothiocyanate yielded stably labeled chitosan molecules, which were successfully formulated into nanoparticles by ionotropic gelation. Uptake of fluorescein-5-isothiocyanate-chitosan nanoparticles and chitosan molecules by confluent A549 cells… CONTINUE READING
