SRF@Fe EGCG nanocomplex. The particle size and Zeta potential of SRF@Fe EGCG nanocomplex and

the mass fraction of each substance in SRF@Fe EGCG nanocomplex were tested. The encapsulation rate

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

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.
