Nanoparticles’ (NPs) properties characterization. After fabrication, NPs were characterized for their physicochemical and biological properties using dynamic light scattering. No significant changes in A) size and B) polydispersity index (PDI) were observed. However, a significant decrease in C) zeta potential for leukosomes (Leuko) compared to liposomes (Lipo) was noticed. D) Representative cryo‐TEM images of Lipo and Leuko verified that no morphological changes occurred following membrane protein integration to the NPs. Scale bars = 100 nm. E) Western blots for leukocyte membrane protein markers: CD11b, CD18, CD47, and CD45 indicated their membrane integration in Leuko but absence in Lipo. Results are shown as mean ± SEM. Unpaired t‐test was used to determine statistical probabilities *p ≤ 0.05 among means considered statistically significant, n = 5.
