RBC microswimmers loaded with DOX molecules preserve their membrane proteins after hypotonic treatment. RBC microswimmers loaded with DOX molecules preserve their membrane proteins after hypotonic treatment. (A) Loading of DOX molecules and SPIONs is achieved via hypotonic dilution technique. (B) RBCs (i) loaded with DOX via hypotonic dilution method (ii) preserve their membrane expression of TER-119 (iii and iv). DIC, differential interference contrast. (C) Flow cytometry density plots obtained from RBCs (i) after hypotonic-isotonic treatment, (ii) DOX encapsulation, (iii) anti–TER-119 staining, and (iv) both anti–TER-119 staining and DOX encapsulation show successful encapsulation of DOX and TER-119 expression. a.u., arbitrary units. (D) Cumulative released percentage of DOX molecules over time (5 days) from RBC cargoes at pH = 3.1, 5.0, 7.2, and 9.2. Yunus Alapan et al. Sci.
