                 and drug loading of SRF in SRF@Fe EGCG nanocomplex were measured. Cell tests in vitro showed that
                 SRF@Fe EGCG nanocomplex had obvious inhibitory effect on the growth of Hela tumor cells, and the
                         Ⅲ
                 survival rate of tumor cells was about 30%. In addition, it was found that the nanocomplex had a synergistic
                 effect on tumor cell growth inhibition in various forms, and induction of cell ferroptosis was indeed one of
                 the ways of action of the nanocomplex.
