Cervical cancer is one of the most occurring cancers and the fourth leading occurrence of cancer in women, worldwide. In this study, we planned to synthesis kappa-Carrageenan grafted graphene oxide nanocarrier conjugated with biotin (GO-kappa-Car-biotin) for targeted cervical cancer. Doxorubicin (DOX) is a well-known anticancer drug for any type of cancer and it is used to entrap over on the graphene oxide surface via pi-pi stacking interaction. The chemical function and crystalline nature of the synthesized nanocarrier was characterized by Fourier Transformed Infrared Spectroscopy (FT-IR) and X-ray diffraction Analysis (XRD). The surface morphological study was carried out through Scanning Electron Microscopy (SEM), Transmission electron microscopy (TEM) and Atomic force microscopy (AFM). The in-vitro drug release profile of DOX was carried out by UV-Vis spectrometer at the lambda(max). value of 480 nm. The entrapment of DOX on GO-kappa-car-biotin has been observed at 94%. The hydrophilic DOX drug has excellent pH-sensitive drug released in an in-vitro study. The anticancer efficiency of the synthesized GO-based nanocarrier was examined using HeLa cell line in-vitro. Cell viability, proliferation, cytotoxicity, and nuclear chromatin condensation was studied by trypan blue assay, triphosphate assay (ATP), lactate dehydrogenase assay (LDH) and Hoechst staining respectively. Finally, biotin leading GO-kappa-Car carrier demonstrated is a promising drug delivery system for cervical cancer treatment.
