College of Science, University of Thi-Qar discussed a Ph.D. thesis on studying of some natural compounds loaded with graphene oxide and their chemical applications for treating breast cancer patients by the postgraduate student, Mrs, Amna Salem Kadhim.

The thesis aimed at synthesizing graphene oxide nanomaterial and biosynthesis of reduced graphene oxide nanomaterial via using the Iraqi sumac plant Rhus coriaria (L.) to use it as an effective and less toxic alternative method for treating breast cancer and as an antibacterial.

The thesis highlighted that the synthesis of graphene oxide (GO) by Hemmer's improved method and reduced graphene oxide (rGO) using plant extracts with different solvents (methanol and ethyl acetate) from different parts (leaves and fruits) of the Iraqi sumac plant Rhus coriaria (L.) by the bioreduction method (biosynthesis) then use diagnostic techniques such as a visible and ultraviolet spectrometer, an infrared spectrometer, an X-ray spectrometer, a Raman spectrometer, a scanning electron microscope and a transmission electron microscope.

The thesis concluded that graphene oxide and reduced graphene oxide prepared by bioreduction method have antibacterial activity against the two types of bacteria studied, as well as higher activity than the antibacterials used and they reviewed anti-cancer activity against breast cancer cells (MCF-7).

The thesis recommended studying the effect of reduced graphene oxide against cells of other types of cancer, such as lung, prostate, colon and liver the effect of reduced graphene oxide against fungi can also be studied.
