However, there are shortcomings with respect to conventional chemotherapy that limit therapeutic efficiency, including lack of tumor selectivity, systemic toxicity and drug resistance. Objective: A multifunctional nanoplatform was build using of hydrogel co-loaded containing cisplatin and Iron oxide–gold core-shell nanoparticles. The Au shell comprises the light response and the iron core can be utilized as a negative contrast agent in nanocomplex.Material and Methods: In this experimental study, KB cells derived from the epithelial cells located in the nasopharynx were exposed to different levels of concentration of hydrogel co-loaded with cisplatin and Iron oxide–gold core-shell nanoparticles. Afterwards, the cytotoxicity was determined using MTT assay. Results: The cytotoxicity results showed that this nanoplatforms has potent to create higher cytotoxicity in KB cells than free cisplatin, so that Fe-Au@Alg and Fe-Au@Alg with cisplatin mixed with laser irradiation exhibited a significant reduction in cell viability after 5 min.  Conclusion: Hydrogel co-loaded with cisplatin and Iron oxide–gold core–shell nanoparticles are stable construct to combine chemo-photothermal therapy. Therefore, they can be used as a computed tomography-traceable nanocarrie, enabling us to monitor the delivery of therapeutics.}, keywords = {Chemo-Photothermal Therapy,Iron Oxide–Gold Core–Shell Nanoparticles,Cisplatin,Nanoparticles,KB Cells}, url = {https://jbpe.sums.ac.ir/article_47379.html}, eprint = {https://jbpe.sums.ac.ir/article_47379_12cb98f3af52c6123c0e0789efe54c25.pdf} }
