Self-assembled nanoparticles based on hydrophobically modified chitosan as carriers for doxorubicin
Abstract
In this study self-assembled nanoparticles based on oleoyl-chitosan (OCH) were prepared with a mean diameter of 255.3 nm and an almost spherical shape. The toxicity profile of OCH nanoparticles was evaluated in vitro via hemolysis test and MTT assay. The hemolysis rates of OCH nanoparticles tested in different conditions came well within permissible limits (5%). The OCH nanoparticles showed no cytotoxicity to mouse embryo fibroblasts. Doxorubicin (DOX) was efficiently loaded into OCH nanoparticles with an encapsulation efficiency of 52.6%. The drug was rapidly and completely released from the nanoparticles (DOX-OCH nanoparticles) at pH 3.8, whereas at pH 7.4 there was a sustained release after a burst release. The inhibitory rates of DOX-OCH nanoparticle suspension to different human cancer cells (A549, Bel-7402, HeLa, and SGC-7901) significantly outperformed that of DOX solution. These results revealed the potential of OCH nanoparticles as carriers for hydrophobic antitumor agents.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
