| Résumé: | Manjri Singh,1 Parul Gupta,2 Richa Baronia,1 Priti Singh,1 Stalin Karuppiah,1 Rishi Shankar,3 Premendra D Dwivedi,2 Surinder P Singh1 1CSIR-National Physical Laboratory, New Delhi, 2CSIR-Indian Institute of Toxicology Research, Lucknow, Uttar Pradesh, 3Institute of Life Sciences, Ahmedabad University, Ahmedabad, Gujarat, India Abstract: We have synthesized graphene oxide (GO) nanosheets using modified Hummer’s method and conjugated it with doxorubicin (DOx), an anticancer drug. Drug release kinetics from GO–DOx conjugate indicated the drug release at acidic pH. MTT assay performed on FaDu hypopharyngeal cancer cell lines revealed that the GO–DOx nanoconjugate inhibited cell proliferation more efficiently compared with pure DOx. Preliminary results indicate the potential of designed GO–DOx drug conjugate for head and neck cancer. Keywords: graphene oxide, doxorubicin, nanomedicine, head and neck cancer |
