a Schematic diagram of E/M@FA-LPs preparation. b The diameter of E/M@FA-LPs performed by DLS is about 174 nm and the zeta potential value was −24 mV. c TEM images of E/M@FA-LPs. The micrographs show spherical particles for the E/M@FA-LPs, with the size of 154 nm. Scale bar represents 100 nm. d Cumulative erastin release from E/M@FA-LPs. All experiments were repeated at least three times and representative data are shown. Data are means ± SEM.
