- W4304080344 abstract "Chitosan (CS)-based pH-sensitive nanocomposites were fabricated for the targeted delivery of doxorubicin (DOX) to osteosarcoma cells. To prepare the nanocomposite, CS was functionalized with succinic anhydride (SA) (CS-SA). CS-folic acid (FA) conjugates were produced by the conjugation of CS with FA via an amide bond. Next, Fe3O4 magnetic nanoparticles (MNPs) ferrofluid was fabricated, and nanocomposite was produced using MNPs and synthesized CS-SA/CS-FA and CS-SA via an inclusion formation between -COOH groups of CS-SA and hydroxyl groups of Fe3O4. Finally, DOX molecules were loaded onto the nanocomposites. The nanocomposites were characterized through FT-IR, DLS, XRD, VSM, TEM, and UV-Vis spectroscopy analyses. DOX release profile at various pHs indicated an enhanced release of DOX in acidic conditions. The cytotoxicity assay demonstrated that the nanocarriers alone were cytocompatible on cells examined. The MG-63 cells, which partly express the folate receptors (FRs), particularly FR-α, showed meaningfully higher cellular uptake of the DOX-loaded CS-FA/CS-SA@MNPs than the FR-negative lung cancer A549 cells. The DOX-loaded CS-FA/CS-SA-MNPs could induce significant cytotoxicity in the MG-63 cells but not in A549 cells. Based on these findings, the DOX-loaded CS-FA/ CS-SA-MNPs might be considered a smart pH-sensitive nanosystem for the targeted delivery of anticancer agents to osteosarcoma cancer cells." @default.
