RESUMO
The graphene-based nanomaterials have been measured as a most promising nanomaterials in the various fields. Graphene oxide having attractive and effective attention in the modified of medicine. Also, graphene oxide is one of the distinct bio-chemical properties with minimum cytotoxicity compared to the other nanomaterials. Up to till date, gastric treatments with reduced graphene oxide not studied so far. In this report, 7-ethyl- 10-hydroxycamptothecin (SN-38) coated graphene oxide synthesized (SN-rGO) effectively and are characterized using various analytical methods. The hydroxyl and carbonyl gatherings of oxidized SN38 will in general ingest onto GO by means of hydrogen bond arrangement with their leftover oxygen functionalities and offers steadiness to SN38. The morphological analyses showed the foldable fields of SN38-rGO NPs with acquire transparency, thin sheets and the crumpled structures. Further the photothermal efficiency and cytotoxicity of the SN-rGO were examined by MTT assay using two NCI-N87 and SGC-791 gastric carcinoma cells. In addition, the morphological changes were examined through the live and dead cells and nuclear staining biochemical techiniques and apoptosis were evaluated through flow cytometry analysis. Our result's suggested that the SN-38 coated reduced graphene oxide can be used for the photothermal treatment of gastric carcinoma for the future nanotechnology cancer therapies without using functionalized polymeric nanoparticles.
