(A) Flow chart summarizing the synthesis steps to prepare freeze thawed or dehydrated and rehydrated vesicles; TEM microgrpahs of (B) freeze-thawed vesicles, (C)dehydrated-rehydrated vesicles; (D) The quenching factor (ΔRFU/Initial RFU) of BPD for Visudyne or nanoPALs. Results are mean +/− s.d.’s (n =4). **p=0.0016 (t-test); (E) TEM micrograph is a representative image of intact nanoPALs without any PDT exposure and nanoPALs exposed to a 1 J·cm−2 light dose, over 20 s, typically employed in the cytotoxicity studies.
