In vitro cell viability of CT26‐luc treated with different formations. A,B) Viability of CT26‐luc cells treated with varying concentrations of OxP or R848 in vitro (n = 3). C) Schematic diagram depicting the construction of a transwell system for co‐incubation of OxP@PLEL and CT26‐luc cells. D) Cell viability of CT26‐luc co‐incubated with blank PLEL, free OxP, or OxP@PLEL for 24, 48, and 72 h (n = 3). Data are presented as mean ± SD. P values were determined by Student's t‐test (**p < 0.01, ***p < 0.001).
