Abstract:
The development of carriers for drug delivery faces significant challenges from a therapeutic perspective. The present study presents an innovative nanocarrier based on combination of functionalized magnetic nanocomposite nano‐chitosan and cisplatin. Hydrophobic drugs such as cisplatin could be delivered using magnetic nanoparticles modified with biocompatible copolymers. This study aimed to determine the antitumor effects of free cisplatin enhancement in cervical cancer cells using cisplatin‐encapsulated Fe 3 O 4 @SiO 2 @N‐Chit‐FA. An additional layer of nanochitosan was coated on top of the magnetic nanocomposite to increase its stability in aqueous solutions. Biocompatibility and cytotoxicity of Fe 3 O 4 @SiO 2 @N‐Chit‐FA‐ cis complex were evaluated against the cervical cancer animal model in C57BL6 mice. An external magnetic field was used to test the in‐vivo uptake and distribution of Fe 3 O 4 @SiO 2 @N‐Chit‐FA‐ cis in tumor cells. The results showed that the released drug would induce its effects on a specific target area when an external magnetic field was applied, and Fe 3 O 4 @SiO 2 @N‐Chit‐FA‐ cis can suppress tumor growth more than cisplatin alone via induction of tumor necrosis. Overall, Fe 3 O 4 @SiO 2 @N‐Chit‐FA nanocomposites hold great potential for use in targeted nanomedicine to deliver bio‐functional molecules.
